∆H and ∆U

[Rita Chen 1B]

Can someone simply explain ∆H and ∆U for me?

[Jasmine Fendi 1D]

Delta H is the change in enthalpy while delta U is the change in internal energy in a system. Most of the time, I think you can use them interchangeably in this class.

[DLee_1L]

You can use delta H and delta U interchangeably when the system has no work done on it and the only thing contributing to delta H is delta U

Delta H is the change in enthalpy of a system while delta U is the change in internal energy accompanied by a reaction. In other words, the difference between delta H and delta U is P x Delta V. So Delta H is the total work done and Delta U is just the work done by the heat of the reaction.
