Enthalpy

Postby Samuel G Rivera - Discussion 4I » Fri Jan 24, 2020 10:29 pm

I'm a little confused about enthalpy. From what I understand, enthalpy is the capacity to transfer heat. Is this the same as energy being the the capacity to do work? The lines between these concepts are a little blurry for me.

Enthalpy is the heat lost or gained by a system in a reaction. Once that heat energy is lost it is available to do work.

When a substance changes at some constant pressure, enthalpy tells how much heat and work was added or removed from the substance!

Enthalpy is made up of the change of the internal energy of the system as well as the pressure and volume which means that it is related to work but comprised of the total energy not just the work energy

Enthalpy encompasses the heat absorbed or evolved in a reaction
