  • Question 1
    4 / -1

    To double the volume of a given mass at an ideal gas at 27o C keeping the pressure constant one must raise the temperature in degree centigrade

  • Question 2
    4 / -1

    At on 0o C pressure measured by barometer is 760 mm. what will be pressure at 100o C

  • Question 3
    4 / -1

    A gas at 27o C has a volume V and pressure P. On heating its pressure is doubled and volume becomes three times. The resulting temperature of the gas will be

  • Question 4
    4 / -1

    A perfect gas at 27o C is heated at constant pressure to 327o C. If original volume of gas at 27o C is V then volume at 327o C is

  • Question 5
    4 / -1

    A vessel contains 1 mole of O2 gas (molar mass 32) at a temperature T. The pressure of the gas is P. An identical vessel containing one mole of He gas (molar mass 4) at temperature 2T has a pressure of

  • Question 6
    4 / -1

    The pressure is exerted by the gas on the walls of the container because

  • Question 7
    4 / -1

    The root mean square speed of hydrogen molecules of an ideal hydrogen kept in a gas chamber at 0o C is 3180 ms–1. The pressure on the hydrogen gas is (Density of hydrogen gas is 8.99 × 10–2 kg/m3, 1 atm = 1.01 × 105 Nm–2

  • Question 8
    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 9
    4 / -1

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

  • Question 10
    4 / -1

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