MHT CET Physics question

For an ideal gas, The change in internal energy in a constant pressure process from temperature to is

(A)equal to, , where is the molar specific heat at constant volume and n is the number of moles of the gas
(B)The change in internal energy of the gas is equal to the work done by the gas in magnitude in an adiabatic process
(C)The internal energy shows no change in an isothermal process
(D)All of options A, B and CCorrect

Answer: (D)

Solution

For an ideal gas for any process (a is true), in an adiabatic process so the magnitudes are equal (b is true),
