H and q

[Funmi Baruwa]

Is heat denoted with q or H? Or is H for heat and q is for enthalpy specifically?

[SophiaNguyen_2L]

I believe q denotes heat, which is basically a transfer of energy in chemical reactions. On the other hand, H is enthalpy, which is a state property.

[Aayushi Jani 3A]

q is the measurement for heat (in joules) and H is for enthalpy. While enthalpy is a state property (not dependent on the path taken to obtain that state), heat is not.

[Jiapeng Han 1C]

I think q typically denotes a change in heat energy while H denotes a change in enthalpy.

[Jiayi Wu 3J]

q is the heat flow and H is enthalpy.

[Inderpal Singh 2L]

H is for enthalpy
q is for heat flow

[Tanner Bartyczak 1K]

q is for heat.
H is for enthalpy.

[Devin Patel 2D]

q is the denotation for heat (in joules), which is not a state property, and H is the denotation for enthalpy, which is a state property.

[Gwirnowski 3B]

H is used to denote enthalpy values while q denotes heat

[Jason_John_2F]

q is energy transfer while h(enthalpy) is total heat content or state of the system

[Ava Nickman]

h is enthalpy and q is heat

[Madison Muggeo 3H]

Q is just the transfer of heat, while H is the enthalpy of the system.

[Ansh Patel 2I]

Hi! H represent the enthalpy of a system and q represents heat.

[Sofia Lombardo 2C]

H represents enthalpy, while q represents the transfer of heat.

[Keon Amirazodi 3H]

h=heat
q=enthalpy

[Shreyank Kadadi 3K]

q refers to heat whereas H refers to enthalpy. Enthalpy is known as a state function, meaning that if you knew the state of a reaction (how the reaction was before and after it occurred), the enthalpy can be calculated. On the other hand, heat is not a state function and cannot be calculated from the starting and ending states of a reaction.

[josephspindler2H]

Q is for heat and H is for enthalpy!

[Luveia Pangilinan 1A]

H is for enthalpy and is a state property and q is not so it's for heat! Hope this helps :D

[Gillian Gabrielsen2F]

ΔH is for enthalpy, which is specifically the energy absorbed/released as heat by a system under constant pressure. It's a state function. Heat, q, is not a state function.

[Isabella Cortes 2H]

H denotes enthalpy and Q is for heat

[David Y]

delta H is a change in enthalpy

[Mingzi Yang 1E]

Heat is denoted with q. H / delta H is for enthalpy.

[Justin Zhang_1A]

q refers to heat while H is enthalpy.

[Ximeng Guo 2K]

H is enthalpy
q is heat energy

[Abraham De Luna]

Q is used to denote heat and H is used to denote enthalpy.

[John Antowan 1K]

The symbol q is intended to express heat and H is to represent enthalpy is a state function while heat is not.

[Funmi Baruwa]

thank you all!

[Xavier Herrera 3H]

q represents the amount of heat released or absorbed in a system in J. Delta H represents the amount of heat released or absorbed AT CONSTANT PRESSURE. So you can think of it like q sub p = deltaH.

[Melis Kasaba 2B]

q is heat, while H is used to describe a change in enthalpy. As we discussed in class, enthalpy is a state function, while heat is focused more on heat released/absorbed from a system.

[Adam Bustamante 1I]

q is for the heat whereas H is for enthalpy.

[Katie Le 3K]

q is heat. h is enthalpy

[reyvalui_3g]

Heat is represented by q.

[rhettfarmer-3H]

Q refers to heat which is not a state property and H is the enthalpy which is a state function.

[Sarah Huh 1K]

q is heat in joules, while H is enthalpy change.

[Faaizah Arshad 1H]

q is the heat that is transferred to or from a system, and it is not a state function. However, H is the total heat of the system at constant pressure and it is a state function.

[Caelin Brenninkmeijer 1G]

H is the enthalpy of the system while q is the amount of heat transferred in a system and is used to describe the change in enthalpy.

[Keshav Patel 14B 2B]

Q represent heat, while H is a state function for enthalpy meaning the change in amount of heat.

[MCalcagnie_ 1D]

I think q represents heat, but its not a state function. H is a state function that represents the net heat of a system at a specific pressure.

[Sahaj Patel Lec3DisK]

"q" denoted heat, while H represents enthalpy. If I am not mistaken, heat (q) of a gas under constant pressure equals the change in Enthalpy (H). Hope this helps!

[Kiana Tashakori 1D]

heat is denoted by q, and enthalpy is denoted by h

[Presley Gao 2C]

Heat is denoted with q and enthalpy is denoted with H, specifically.

[Carly_Lipschitz_3H]

Q represents heat/energy but is not a state function. H is representative of enthalpy and is a state function.

[Mina Tadros 3L]

Heat, which is not a state function, is denoted by q, while enthalpy, which is a change in heat at constant pressure, is a state function, and thus, it is denoted by delta H.

[Lizbeth Garcia 1F]

I believe q can also be used for enthalpy if it is qp or heat absorbed/released at constant pressure.

[Charisma Arreola 2F]

Q denotes heat and H is enthalpy.

[Kyla Roche 2K]

H is for enthalpy and q is for heat but when q is under constant pressure, q=h. This is because enthalpy relates to heat under the terms of constant pressure.

[Navdha Sharma 3J]

Q --> heat
H --> enthalpy

[Zainab Jamali 1H]

q is the measurement of heat (transfer of heat energy) and H is the measurement of enthalpy! Enthalpy is a state function but heat is not. If the system in question is at constant pressure, then I believe delta H is equal to q.
