  • Question 1
    4 / -1

    At temperature T, the r.m.s. speed of helium molecules is the same as r.m.s. speed of hydrogen molecules at normal temperature and pressure. The value of T is

  • Question 2
    4 / -1

    At a given temperature the r.m.s velocity of molecules of the gas is

  • Question 3
    4 / -1

    At a given temperature the ratio of r.m.s. velocities of hydrogen molecule and helium atom will be

  • Question 4
    4 / -1

    If the oxygen (O2) has root mean square velocity of C ms–1 then root mean square velocity of the hydrogen (H2) will be

  • Question 5
    4 / -1

    The temperature of an ideal gas is reduced from 927°C to 27°C. The r.m.s. velocity of the molecules becomes

  • Question 6
    4 / -1

    The r.m.s. speed of the molecules of a gas in a vessel is 400 ms–1. If half of the gas leaks out, at constant temperature, the r.m.s. speed of the remaining molecules will be

  • Question 7
    4 / -1

    Cooking gas containers are kept in a lorry moving with uniform speed. The temperature of the gas molecules inside will

  • Question 8
    4 / -1

    The gas having average speed four times as that of SO2 (molecular mass 64) is

  • Question 9
    4 / -1

    The root mean square speed of hydrogen molecules at 300 K is 1930 m/s. Then, the root mean square speed of oxygen molecules at 900 K will be
