Heat vs. Enthalpy

Postby Sanjana Munagala_1j » Fri Jan 24, 2020 6:10 pm

What is the difference between heat(q) and enthalpy? I know heat is not a state property and enthalpy is a state property. Also are the two related somehow as well? Please let me know!
Thanks!

enthalpy is the study of heat released or absorbed in chemical reactions and physical changes. Heat is the energy transfer that results from a change in temperature between an object and its environment.

I think enthalpy is more of the change occurring with heat during a rxn.

The total heat added to or lost from a system is the enthalpy. Enthalpy can only be calculated if the system is at a constant pressure. Heat is just the difference in temperature

Enthalpy is the change of heat in a chemical reaction, while heat is a more general term.

heat released is a factor when calculating enthalpy for a given system.

Does that mean enthalpy accounts for the change in heat?
