Entropy vs. Enthalpy

[Alondra Cortes 1F]

What are the differences between the two? Is there a correlation between them?

[Victor Yao 1G]

Enthalpy and entropy are both thermodynamic properties that help to describe the state of system. Enthalpy is a measure of the total energy of a system, while entropy is the measure of how random or how disordered a system is.

[DylanNgo3F]

Enthalpy(H) is the amount of heat released or absorbed at a constant pressure. Entropy(S) is the disorder within a compound. They both together form the change of free energy (delta G) in the equation Delta=DeltaH-T*(DeltaS).

[Akilah Beatty 2k]

Enthalpy measures the total amount of energy whereas entropy measures the disorder.

[hannah]

As the people before me said, enthalpy is the total energy of a system whereas entropy describes how much disorder or randomness there is. I do not believe there is a direct correlation between the two, so try to think of them separately.

[kate cassiano 1F]

Enthalpy is measuring the amount of disorder whereas enthalpy is related to the amount of heat in a reaction. Enthalpy can be written in formula form as H= E +PV (heat= energy + pressure * volume).

[Amber1L]

Enthalpy refers to the amount of heat in a thermodynamic system whereas entropy refers to the level of order within a thermodynamic system.

[905775469]

Enthalpy measures the amount of heat releases of a system and when there is constant pressure Q=deltaH. Entropy measures disorder and is releated to degerneracy W through the equation S=KblnW.

[Niyati 1F]

Enthalpy is the energy or heat of a system. Entropy is the randomness of a system.

[Hope_Hayashida_3E]

Enthalpy (H) is the amount of internal energy/heat a system has, whereas entropy (S) is the amount of disorder the system has. I think we're going to learn it later, but Gibbs free energy (G) combines these two into a single value.

[Casey Fineberg]

Entropy and enthalpy are both thermodynamic properties that describe the current state of a system. However, while enthalpy is a measure of the total energy of a system, entropy is the measure of the randomness/disorder of a system.

[Ishika Gupta 3E]

Enthalpy is the amount of internal energy in a system while enthalpy is the amount of disorder in a system. Entropy is the measure of change in enthalpy/temperature.

[Emily Lam 2H]

Honestly I was also quite confused on this as well. But from what I understand enthalpy is the sum of all the total energies and entropy is a measure of the change in enthalpy or temperature.

[Ashwin Kumar 3D]

Although Entropy and Enthalpy are both thermodynamic properties that are used to describe the current state of a system, enthalpy is a specific measure of the total energy of a system, and entropy is the measure of randomness or disorder of the system. Hope this helps!

[Kylie Cheng 1G]

Enthalpy relates to the energy in the system while entropy relates to the disorder that arises from it. They are also calculated using different equations and related to different factors in thermochemistry. Both are very important to understanding how a reactions works.

[Isabel Pon 1D]

Hi! As others have said before, enthalpy is the total energy in a system while entropy is the amount of disorder in a system.

[305568482]

The difference between the two is that enthalpy and entropy is that enthalpy is represented as the total heat content and entropy is the degree of disorder in the system.

[Maya_Panozzo_2D]

Does the entropy tell us anything about the molecule? Like what does being disorderly mean for the molecule?

[joannar]

Hello!

So enthalpy is represented as the total heat content, which can be said to be the sum of all the energies while entropy is the degree of disorder and measures randomness in a system

[Tony Wu 2D]

Entropy measures how disorganized the system is, while the change in Enthalpy is the change in the system's overall energy.

[Benjamin Rashti]

Entropy=disorganization=S, on the other hand, Enthalpy=heat=H. The general rule of thumb is that the more Enthalpy, the more Entropy.

[Kimberly_Wu_3H]

Entropy is the degree of disorder in a system, while enthalpy is the total energy of a system.

[renee chowdhry 1A]

What are the differences between the two? Is there a correlation between them?

Enthalpy is the study of heart released or absorbed in chemical reaction and physical changes. Entropy is the measure of a system's thermal energy and is a maximum at equilibrium.

[Tiffany Ngan 1K]

Enthalpy is the total heat content contained in a compound whereas entropy is the amount of intrinsic disorder within the compound.

[Kylie Heering 1D]

Simply put:
Entropy (S) is the amount of disorder in a system. Enthalpy (H) is the amount of heat in a system.
Hope this helps!

[Sean_Hertel_3A]

Hi! Entropy is a measure of disorder in a system, while enthalpy is a measure of heat/energy in a system. Both are important to understand when examining the thermodynamics of a reaction. Hope this helps!

[annaneiger]

Hi! Both are state functions and thermodynamic properties. Enthalpy is the measure of the total energy of a system, normally measured in heat, whereas entropy is the measure of the total amount of disorder in a system. A negative enthalpy implies an exothermic rxm, releasing heat, whereas a positive enthalpy implies an endothermic rxn, absorbing heat. A negative entropy implies a decrease in disorder, whereas a positive enthalpy implies an increase in disorder. Hope this helps!

[Michelle Lim 2G]

HI! Enthalpy(H) and Entropy(S) are both thermodynamic properties. Enthalpy is a measure of the total energy of a system, while entropy is the measure of how srandom a system is.

[205756817]

Enthalpy tells us the amount of heat produced or consumed by the reaction at constant pressure and is denoted by delta H.

While Entropy is the measure of disorder in the reaction and is denoted by S.

During phase change, The entropy of vaporization, fusion is equal to S= H/T vap and s= H/T fusion respectively.

[GPena1F]

What are the differences between the two? Is there a correlation between them?

Conceptually, entropy is the amount of intrinsic disorder within a substance, whereas enthalpy is the quantity of internal energy.

[Brandy_Lopez_1C]

Hi!

We can identify entropy as the amount of disorder in a system. This can refer to how much energy is available to do work. When the entropy is higher there is more disorder and less energy available to do work.

Enthalpy is the heat released or absorbed at constant pressure. When the enthalpy is negative it releases heat and when the enthalpy is positive it absorbs heat.

Hopefully, that helps!
