Two moles of ideal helium gas are in a rubber balloon at 30° C .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 35°C.The amount of heat required in raising the temperature is nearly (take R = 8.31 J/mol.K)

Verified by ExpertsThe correct answer is:
D
Δ Q = nC P Δ T
= 2 
Δ T
= 2 
× 5
= 2 × 
× 8.31 × 5
= 208 J
