  • Question 1
    4 / -1

    ΔU + ΔW = 0 is valid for

  • Question 2
    4 / -1

    Air is filled in a motor tube at 27° C and at a pressure of 8 atmospheres. The tube suddenly bursts, then temperature of air is [Given γ of air = 1.5]

  • Question 3
    4 / -1

    One mole of an ideal gas with γ = 1.4, is adiabatically compressed so that its temperature rises from 27°C to 35°C. The change in the internal energy of the gas is (R = 8.3 J mol.K)

  • Question 4
    4 / -1

    A gas for which γ = 1.5 is suddenly compressed to 1/4th of the initial volume. Then the ratio of the final to the initial pressure is

  • Question 5
    4 / -1

    The internal energy of the gas increases in

  • Question 6
    4 / -1

    A gas expands under constant pressure P from volume V1 to V2 . The work done by the gas is

  • Question 7
    4 / -1

    Work done by 0.1 mole of a gas at 27°C to double its volume at constant pressure is (R = 2 cal mol–1° C–1)

  • Question 8
    4 / -1

    If 300 ml of a gas at 27°C is cooled to 7°C at constant pressure, then its final volume will be

  • Question 9
    4 / -1

    In which thermodynamic process, volume remains same ?

  • Question 10
    4 / -1

    In an isochoric process if T1 = 27° C and T2 = 127° C, then P1/ P2 will be equal to
