Internal energy produces heat and heat creates work. Internal energy is in gasses. Also, presurinzing gas allows the gas to do work. Basically, the work done depends on the pressure of the gas.
Gas can lift and turn objects. If it is compressed, it can shoot out and release energy. This energy does work. Wind can turn turbines. It can lift airplanes. It can do all sorts of work.

It has to deal with internal energy and gasses. Internal energy can be used to do work. The work done has to deal with the pressure of the gas.
It produces heat and that creates work son. The pressure of the gas is what allows it do to work.
Work done by a gas equals pressure times volume change. The internal energy produces heat and that heat creates work. Gas uses energy to produce work.
Internal energy produces heat. The higher the internal energy the mmore work done. There for the higher the heat the more the work.
