State property

[IreneSeo3F]

What is the definition of state property? Why are heat and work not considered as state properties?

[Hazelle Gunawan 3G]

A state property is the same no matter what path you take to get to it. Work and heat aren't considered state properties because they can change depending on what steps you take to get to the end product.

[Savana Maxfield 3F]

Adding on to the above reply, a state function does not depend on the path taken. A path function (work and heat) depends on the path taken!

[Emily Tieu 2K]

A state property is determined by its current state, meaning that only the final value is important and not the path taken to get to that value. Therefore, state properties can be added and subtracted to find their value (final state minus initial state). Examples of state properties are Entropy, Pressure, Volume, Temperature, Density, Heat Capacity, Internal Energy, and Enthalpy. Work and Heat are not state properties because they are dependent on the path taken, meaning that they are defined by how it's changed from point A to point B. However, heat at constant pressure would then be enthalpy and thus a state property.

[Ranen_Chang_2G]

State properties only consider the current state, so only taking the final and initial states in account. This implies it is independent of the path taken to get there, unlike work or heat.

[SelenaDahabreh1D]

A state property only takes into account the initial and final states. Heat and work are not considered state properties because they are path dependent.

[Crystal Hsueh 2L]

Just like the above replies said, state properties only care about where the process starts and where it ends. There is a very helpful image/diagram in the textbook that analogizes state and path properties as climbing a mountain that you should check out if you need a visual

[Lesly Lopez 3A]

I believe the state property should be the same no matter how you get to the final part. Taking this into account, work and heat are not considered state properties. This is because their values can change depending on what certain steps that are made take to get to the end value.

[Giselle_zamora_1L]

A state property doesn't depend on the path taken. For example the distance between your house and UCLA. The distance does not change since its fixed but I'm sure you can take shortcuts it longer ways that can increase or decrease the actual miles it takes you to reach UCLA. In the same way temperature (a state property) doesn't depend on how many times you changed it , only the initial and final temperatures.

[Ziyan Peng 3A]

A state function does not depend on the path taken while properties like work and heat describe the path taken.

[Kyla Roche 2K]

A state property isn’t affected by the path taken therefore you can add and subtract the values. Otherwise, variables such as work and heat energy do take the path taken into account

[Kimiya Aframian IB]

What is the definition of state property? Why are heat and work not considered as state properties?

Hi! A state property is not dependent on the path that the system travels in reaching the end result, but instead it is only dependent on the final and initial conditions. I think of it as climbing a mountain: one thing to consider is the change in altitude which does not depend on what path was taken, and another is how far I have walked (especially if I took the long path this would be different than the altitude). Heat and work are dependent on the path taken, which makes them not state properties. Hope this helps!

[Sara Sandri 2B]

A state property is essentially uninfluenced by the path traveled. State properties just depend on the final and initial state. For example, temperature is a state property but work is not.

[Jason Knight - 1F]

A state property contains a value that is determined by the final and initial states of the system. On the other hand, work and heat are not state properties because they are determined by the progress of the system from one state to another.

[305572629]

Heat and work are not considered state properties because they are affected by the paths that they take and are changed by them.

[SamayaJoshi1A]

What is the difference between a state function and U/T?

[Jay Solanki 3A]

What is the difference between a state function and U/T?

I don't think there is a difference. U represents internal energy and T represents temperature, both of which are state functions. I hope that answered your question!!

[David Y]

State properties do not take into account the path taken to get the final result. It is just final minus initial.

[Jiwon_Chae_3L]

If something is a state property, that means that the different steps in a process that might have occurred in between an initial and final state are irrelevant. State functions can be described in net terms.

[FrancescaHawkins2H]

State properties are measurements that do not change based on the path taken to get the measurement. For example, we could increase and decrease the volume of a container numerous times, but the delta V is still going to be Vfinal-Vinitial, regardless of these intermediate changes.

[Jeremy Wei 2C]

Hi, state properties don't take into account the path taken to achieve the final value. So, work and heat aren't state properties since they do take into account the path.

[Esmeralda_Solis_2D]

State property is a system that depends only on current conditions such as temperature and volume etc; not on its history and/or path.

[605721741]

Enthalpy just looks at initial heat and final heat, and not the path in between, which is why it is a state function.

[Tammy Shen 2L]

State properties/functions are additive. The path taken to reach the end result does not dictate the state property.

[Eric Sun 2G]

A state property a value determined by its current state and not dependent on the path taken to obtain the state. Professor Lavelle said that some state properties are Pressure, Volume, Temperature, Density, Heat Capacity, Internal Energy, and Enthalpy. Work and Heat are dependent on the path taken, meaning that they are defined by how it's changed from its starting state until its current state, and results in why they are not state properties.

[Fiona H 2E]

A state property is a quantity that is independent of how the substances was prepared. Some examples are pressure, volume, temperature, and internal energy.

[Chris Korban 1D]

State properties only measure the Final values of something- the initial value and do not consider intermidary steps like the path taken. However, Work and heat vary with the path as the longer it takes you to get to that final destination, it may take more work to do so

[Sara Dolmo 2J]

State functions/ property doesn't depend on the path taken but the path function is the opposite and it does depend on the path taken

[Windell Viste 1K]

State properties only take into consideration its current state, so its final and initial states, no matter the path taken to get to that current state, I believe.

[Hannah Carsey 1B]

A state property is a quantity that is independent of / not reliant on how the substance was prepared, it is a value that is determined by the current state of the substance (like altitude, pressure, volume, temperature, internal energy, etc.).

[isabella garcia - 1G]

State properties are measured only by their current state, with the path taken to reach that state not being taken into account when determining it.

[Ivy Vo Dis 1C]

State properties only take into account the initial state. This means that the path taken to complete a process does not matter. Work and heat take into consideration the path taken. A longer path would result in more work done and more heat produced.

[Chelsea Tran 3H]

State property is independent of the path taken. Work and heat depend on the path taken.

[Mario Prado 1K]

Hello,

A state property doesn't care about the path taken. Heat and work cannot be considered state properties because the path taken can change the results.

Hope this helps.

[Om Patel]

s state property is a value you get no matter what path you take to get to it

[Jessica Sun 2I]

state properties are values that do not depend on the path it takes to get to their states. Work and heat are dependent on the path it takes to get to the values so they are not state properties. Heat is only a state property when it is under constant pressure which makes it enthalpy.

[Arshaun Faraji 2H]

A state property specifically looks at the beginning and final states.

Heat and work are not state properties because the path taken is important, whereas a state property only needs the beginning and final states.

[kayleec1004]

A state property is determined by its current state. Only the final value is important (not the path taken to get to that value). This means that state properties can be added/subtracted to find their value (final - initial).
Be careful! Work/heat are NOT state properties because they are dependent on the path taken. This means that they are defined by how it's changed from point A to point B. BUT heat at constant pressure (Cp) is enthalpy so a state property.

[Tristan Friet 3G]

A state property independent of the path taken. Therefore heat is not a state property as it changes.

[605721741]

They are state properties because the path does not matter. Therefore, they can be additive.

[Alice Weber 3I]

A state property only considers the initial and final state of a reaction.

[Sophia Dominguez 3I]

A state property is a value that is determined by its current state. A state property is not dependent on the path taken to obtain that state. State properties can be added and subtracted. State properties include E, P, V, T, density and heat capacity. Work and heat are not considered state properties because they depend on the path taken.

[JennyZhu1K]

A state property is a property that does not depend on the pathway that a reaction takes. These inclue enthalpy, entropy, and gibb's free energy. Non-state properties include work and rate constants.

[Nick Oscarson 1K]

State properties do not require a specific pathway to get to whichever state is needed. Therefore, examples include pressure, temperature, volume, mass, density, internal energy, enthalpy, entropy, Gibb's free energy, etc.

[kaylasaens2A]

A state property is a value that is independent of the pathway that reaction takes. Examples of state properties include entropy, enthalpy, and gibb's free energy. Heat and work are not considered state properties because they are dependent on the path taken. Heat and work are examples of path functions.

[605823283]

state properties are not determined by the path taken and is independent of how it was prepared.

[Sarthika Chimmula 3H]

A state property is independent of how the substance was prepared. Work and heat are not state properties because they depend on the path used to go from the initial to the final state.

[Zoe Staggs 3B]

A state property has a definite start and end point, regardless of the path taken to get there. For example, change in entropy is the same in reversible and irreversible processes, making it a state funcruin.
