During an adiabatic expansion of 2 moles of a gas, the change in internal energy was found – 50 J. The work done during the process is

During an adiabatic process, the pressure of a gas is found to be proportional to the cube of its absolute temperature. The ratio C_p/C_v for the gas is

In adiabatic expansion of a gas

Which property of the system does not change in an adiabatic process?

5.6 litres of helium gas at STP is adiabatically compressed to 0.7 litre. Taking the initial temperature to be T₁, the work done in the process is

In changing the state of a gas adiabatically from an equilibrium state A to another equilibrium state B, an amount of work equal to 22.3 J is done on the system. If the gas is taken from state A to B via a process in which the net heat absorbed by the system is 9.35 calories, the net work done by the system in latter case will be

A thermally insulated vessel contains an ideal gas of molecular mass M and ratio of specific heats γ . It is moving with speed v and is suddenly brought to rest. Assuming no heat is lost to the surroundings, its temperature increases by

A gas is compressed at a constant pressure of 50 N/m² from a volume of 10 m³ to a volume of 4 m³. Energy of 100 J then added to the gas by heating. Its internal energy is

In which process the PV indicator diagram is a straight line parallel to volume axis?
