In the initial state, an ideal gas has pressure p1, volume V1 and temperature T1. Now the gas changes its state by effecting a state change so that it reaches the pressure p2, the volume V2 and the temperature T2 in the new state. The pressure doubles during this state change, which is an isochore process.
a) Find the work W performed during the isochore process.
b) The heat Q is exchanged between the gas and the surroundings during the isochore process. Break the ideal gas law as a starting point, and discuss the sign of heatQ from the gas to the surroundings to the gas?
