  • Question 1/10
    4 / -1
    The temperature of a hypothetical gas increases √2 to times when compressed adiabatically to half the volume. Its equation can be written as
    Solutions

  • Question 2/10
    4 / -1
    Two Carnot engines A and B are operated in succession. The first one, A receives heat from a source at T1 = 800 K and rejects to sink at T2K. The second engine B receives heat rejected by the first engine and rejects to another sink at T3 = 300 K. If the work outputs of two engines are equal, then the value of T2 is
    Solutions

    Solutions

  • Question 6/10
    4 / -1
    Two samples A and B of a gas initially at the same pressure and temperature are compressed from volume V to V/2 (A isothermally and adiabatically). The final pressure of A is
    Solutions

  • Question 7/10
    4 / -1
    Initial pressure and volume of a gas are P and V respectively. First it is expanded isothermally to volume 4V and then compressed adiabatically to volume V. The final pressure of gas will be (given γ = 3/2)
