... We could equally well write this as Work done by band = – Fx To see the point of this, suppose we allow the band to contract, exerting a pull F. In this case x is negative so the work done by the band is positive, which makes sense. If we stretch the band a lot, then F will change significantly du ...

... The total energy of the gas is also a state variable. That is, it depends on one or more of P, V and T. In fact, for a fixed quantity of an ideal gas the total energy depends just on the temperature. We can change the state of the gas in various ways: by some combination of heating it or doing work ...
