  • Question 1
    4 / -1

    The average translational energy and the r.m.s. speed of molecules in a sample of oxygen gas at 300 K are 6.21 × 10–21J and 484 m/s respectively. The corresponding values at 600 K are nearly (assuming ideal gas behaviour)

  • Question 2
    4 / -1

    A polyatomic gas with n degrees of freedom has a mean energy per molecule given by
    (N is Avogadro\'s number)

  • Question 6
    4 / -1

    The average kinetic energy of a helium atom at 30°C is

  • Question 7
    4 / -1

    The kinetic energy of one mole gas at 300 K temperature, is E. At 400 K temperature kinetic energy is E\'. The value of E\'/E is

  • Question 8
    4 / -1

    The capacity of a vessel is 3 litres. It contains 6 g oxygen, 8 g nitrogen and 5 g CO2 mixture at 27°C. If R = 8.31 J/mole × kelvin, then the pressure in the vessel in N/m2 will be (approx.)
