For gas undergoing isobaric expansion, there needs to be heat transfer in order to keep the pressure constant, and this heat changes the internal energy of the system as well as doing work. An isochoric process takes place at a constant volume.

As a result, the change in internal energy of the system is entirely due to the heat transferred. An adiabatic process is one that occurs without heat exchange between the system and the environment. Lee Johnson is a freelance writer and science enthusiast, with a passion for distilling complex concepts into simple, digestible language.

He's written about science for several websites including eHow UK and WiseGeek, mainly covering physics and astronomy. He was also a science blogger for Elements Behavioral Health's blog network for five years. He studied physics at the Open University and graduated in From the point of view of the first law of thermodynamics , this means that the internal energy of the system is unchanged, since temperature is a measure of the average kinetic energy of molecules within the system.

What these equations mean is that the work input to a system must be exactly balanced by a heat output, and vice versa. This can also be thought of as calculating the area under the curve. However, due to the shape of the curve, it's not as simple of a calculation—in comparison to an isobaric process, for example.

The formula below is the integrated equation, and will calculate the work done for any isothermal process:.
