in the second paper question no 8 (code 0)...
Two moles of ideal helium gas are in a rubber balloon at 30c. The balloon is fully expandable and can be assumed to require no energy in its expansion. The temperature of the gas in the balloon is slowly changed to 35c. the amount of heat required in raising the temperature is nearly...
in the question it is given that no energy is required in expansion, i.e W=0
Therefore q = U = n(f/2)RT
rather than n((f/2)+1)RT
plz help...
