What is the effect on the volume of 1 mole of an ideal gas if both the pressure and the temperature are reduced to one- third of their initial values? Explain.
ANSWER
The effect of temperature and pressure on the volume of ideal gas can be estimated by ideal gas equation:
PV = nRT
P1V1 / T1 = P2V2 / T2
P1, V1 and T1 = initial pressure , volume and temperature respectively
P2 , V2 and T2 = final pressure , volume and temperature respectively
V2 = (P1V1 T2 / P2 T1 ) =======1)
P2 = P1 / 3 and T2 = T1 / 3
Substituting these values in equation (1)
V2 = (3 P1V1 T1 / 3 P1 T1 ) = V1
Hence final volume = initial volume. Thus there is no change in the volume of the gas.
