  • Q1 · Behaviour of Perfect Gases and Kinetic Theory · MEDIUM

    If the molecular mass of a gas is doubled at constant temperature, its rms speed becomes:

  • Q2 · Behaviour of Perfect Gases and Kinetic Theory · EASY

    Number of degrees of freedom of a rigid diatomic gas molecule (at moderate temperature) is:

  • Q3 · Behaviour of Perfect Gases and Kinetic Theory · EASY

    A container holds 2 moles of an ideal gas at temperature 300 K. If the temperature is increased to 600 K while keeping the volume constant, what happens to the pressure of the gas?

  • Q4 · Behaviour of Perfect Gases and Kinetic Theory · MEDIUM

    The root mean square (rms) speed of oxygen molecules (O2, molecular mass = 32 g/mol) at 27°C is approximately 484 m/s. What will be the rms speed of hydrogen molecules (H2, molecular mass = 2 g/mol) at the same temperature?

  • Q5 · Behaviour of Perfect Gases and Kinetic Theory · HARD

    A monoatomic gas and a diatomic gas (at moderate temperature) both have the same total kinetic energy. If the monoatomic gas has 'n' molecules, how many molecules does the diatomic gas have?
