  • Question 1
    4 / -1

    A box contains n molecules of a gas. How will the pressure of the gas be effected, if the number of molecules is made 2n?

  • Question 2
    4 / -1

    A cylinder of capacity 20 litres is filled with H2 gas. The total average kinetic energy of translatory motion of its molecules is 1.5 × 105 J. The pressure of hydrogen in the cylinder is

  • Question 3
    4 / -1

    The root mean square speed of hydrogen molecules of an ideal hydrogen gas kept in a gas chamber at 0°C is 3180 m/sec. The pressure on the hydrogen gas is (Density of hydrogen gas is 8.99 × 10–2 kg/m3, 1 atmosphere = 1.01 × 105 N/m2)

  • Question 4
    4 / -1

    Consider a gas with density ρ and ¯c as the root mean square velocity of its molecules contained in a volume. If the system moves as whole with velocity v, then the pressure exerted by the gas is

  • Question 5
    4 / -1

    One kg of a diatomic gas is at a pressure of 8 × 104 N/m2. The density of the gas is 4 kg/m3. What is the energy of the gas due to its thermal motion?

  • Question 6
    4 / -1

    For a diatomic gas change in internal energy for unit change in temperature for constant pressure and constant volume is U1 and U2 respectively. U1 : U2 is

  • Question 7
    4 / -1

    The average kinetic energy of a gas at –23° C and 75 cm pressure is 5 × 10–14 erg for H2. The mean kinetic energy of the O2 at 227°C and 150 cm pressure will be

  • Question 8
    4 / -1

    The ratio of mean kinetic energy of hydrogen and nitrogen at temperature 300 K and 450 K respectively is

  • Question 9
    4 / -1

    The average kinetic energy of a gas molecules can be determined by knowing

  • Question 10
