Enthalpy vs Internal energy

Postby Samantha Man 1L » Fri Feb 01, 2019 1:05 am

What is the difference between the enthalpy of a system and the internal energy of a system?

"enthalpy (H), is the sum of the internal energy of the system plus the product of the pressure of the gas in the system times the volume of the system."

Enthalpy includes internal energy. Internal energy includes both kinetic and potential energy but enthalpy measure the total thermo potential so it adds on the pressure times volume part.

Is there a difference between the SI units of enthalpy and internal energy?

I don't think there is a difference, I think the SI units for both are in joules
