  • Question 1
    4 / -1

    One mole of an ideal gas at an initial temperature of T kelvin does 6R joules of work adiabatically. If the ratio of specific heats of this gas at constant pressure and at constant volume is 5/3, the final temperature of gas will be

  • Question 2
    4 / -1

    The temperature of the system decreases in the process of

  • Question 3
    4 / -1

    An ideal gas expands isothermally from a volume V1 to V2 and then compressed to original volume V1 adiabatically. Initial pressure is P1 and fmal pressure is p3. The total work done is W. Then,

  • Question 4
    4 / -1

  • Question 5
    4 / -1

    Initially, two gas samples 1 and 2 are at the same condition. The volume of the two are halved, one isothermally and the other adiabatically. What is the relation between the final pressure P1 and P2?

  • Question 6
    4 / -1

  • Question 7
    4 / -1

    Ten moles of an ideal gas at constant temperature 500 K is compressed from 50 L to 5 L. Work done in the process is (Given, R = 8.31 J – mol -1 – K -1)

  • Question 8
    4 / -1

    A given mass of a gas is compressed isothermally until its pressure is doubled. It is then allowed to expand adiabatically until its original volume is restored and its pressure is then found to be 0.75 of its initial pressure. The ratio of the specific heats of the gas is approximately
