Insert the information in the form and the calculator will determine the enthalpy.

What is the enthalpy?

The enthalpy is a property of a thermodynamic system, basecly it is the sum of the system's internal energy and the product of it's pressure and volume. In simple words the enthalpy is the system's heat energy.

How to calculate enthalpy?

To calculate enthalpy you should use the following formula:
H = E + P * V
where:
H = enthalpy
E = internal enrgy
p = pressure
v = volume

Why use enthalpy?

The enthalpy is usually used in order to know how much heat (energy) is in a system and by knowing the amount of heat in a system we can derive valuable work formit.
