A container having 1 mole of a gas at a temperature ${27^0}C$ has a movable piston which maintains at constant pressure in container of 1 atm. The gas is compressed until temperature becomes ${127^0}C$. The work done is ( C for gas is 7.03 cal / mol – K)

Which thermodynamic process occurs at constant pressure?

An ideal gas at STP is contained in a thermally insulated chamber A, connected by a valve to an identical evacuated chamber B. Upon opening the valve, the gas expands into chamber B. Which thermodynamic variable remains constant during this process?

During an adiabatic process, the pressure of a gas is found to be proportional to the cube of its absolute temperature. The $\gamma$ of the gas is

One mole of an ideal gas requires 207 J heat to raise the temperature by 1K, when heated at constant pressure. If the same gas is heated at constant volume to raise the temperature by the same range, the heat required will be ($R = 8.3{\rm{Jmo}}{{\rm{l}}^{ - 1}}{{\rm{K}}^{ - 1}})$)
