The change in the magnitude of the volume of an ideal gas when a small additional pressure P is applied at a constant temperature, is the same as the change when the temperature is reduced by a small quantity T at constant pressure. The initial temperature and pressure of the gas were 300 K and 2 atm respectively. If  |ΔT|=C|ΔP| then value of C in (K/atm)  is __________

Solution

PV=nRT

PΔV+VΔP=0

ΔV=-ΔPPV  ....(i)

  In second case

PΔV=-nRΔT

ΔV=-nRΔTP    ...(ii)

equating (i) and (ii)

nRΔTP=-ΔPPV

ΔT=ΔP VnR

c=vnR

Putting the value of V, n and  R , C = 150
