Difference between Delta H and q?

[jonathanshi_1A]

I'm a little confused as to the difference between the two, as they both have to do with heat.

[Rachel_Prescott_2M]

q is the amount of heat transferred to a system whereas is used to describe the change in enthalpy. Enthalpy is the total potential energy of a system, which is associated with the heat transferred to/from a system (q). However, at constant pressure which can make it difficult to see the difference between what the two values are. Hope this helped a bit!

I guess in simpler terms you can say q = heat in general, whereas H (enthalpy) = qp which is heat at a constant pressure.

[Tycho_Meimban_2B]

Q is the energy transfer due to thermal reactions such as heating water, cooking, etc. anywhere where there is a heat transfer. You can say that Q (Heat) is energy in transit.

Enthalpy (Delta H), on the other hand, is the state of the system, the total heat content.

They both can deal with heat (q_p) (Q at constant pressure) = (Delta H) but both Heat and Enthalpy always refer to energy, not specifically Heat.

Hope this helps!
