Three separate reversible processes (1,2 and 3) are carried out with 1 mole of an ideal gas initially at STP. In these processes, the pressure ( P ) is measured while increasing any one of the quantities volume (V), temperature (T) and number of moles (n), keeping the other two constant. Plots of P (atm) versus X are found to be linear, where X = n or T ( K ) or 1 / V ( lit ⁻¹ ) . For the processes 1,2 and 3 , the nu
