An ideal gas described by T(initial)=300K,P(initial)=1 bar and V(i)=10 L is heated at constant volume until P=10 bar. It then undergoes a reversible isothermal expansion until P=1bar.It is then restored to its original state by the extraction of heat at constant pressure. Calculate w for each step.
Initial pressure PI = 1 bar = 1.0*105 Pa
Initial volume VI = 10 L = 0.01 m3
Initial temperature TI = 300 K
When a gas expands, it has to push the atmosphere or the environment back and in this process it is doing work. The work done by an ideal gas in any process is given by
Here VI is the initial volume of the gas and VF is the final volume of the gas.
(The work done by the gas is taken positive and that on the gas is ...
