Question

Assertion: When a bottle of cold carbonated drink is opened a slight fog forms around the opening. Reason: Adiabatic expansion of the gas causes lowering of temperature and condensation of water vapours.

Assertion: In adiabatic compression, the internal energy and temperature of the system get decreased. Reason: The adiabatic compression is a slow process

Assertion: The specific heat of a gas is an adiabatic process is zero and in an isothermal process is infinite. Reason: Specific heat of a gas in directly proportional to change of heat in system and inversely proportional to change in temperature.

Assertion: Work done by a gas in isothermal expansion is more than the work done by the gas in the same expansion, adiabatically. Reason: Temperature remains constant in isothermal expansion and not in adiabatic expansion
