So in my coursebook it says Enthalpyenthalpy is a property that accounts for the increase in internal energy and the accompanying work done by the system and that its equal to the sum of the Internal Energyinternal energy U$U$ and Productproduct of Pressurepressure P$P$ and volume V$V$. Also on the net, mostly on the internet it says:

"A thermodynamic quantity equivalent to the total heat content of a system. It is equal to the internal energy of the system plus the product of pressure and volume."

A thermodynamic quantity equivalent to the total heat content of a system. It is equal to the internal energy of the system plus the product of pressure and volume.

And where it explains in other words i dontI don't quite understand, ege.g. as on wikipediaWikipedia. So please iI would like anyone of you to explain  (in beginner terms) that what is the meaning of enthalpy and heat content as used in the definition above.

THANKS !

What is the qualitative definition of enthalpy in beginner terms?
