  • Question 1
    4 / -1

    The pressure and volume of saturated water vapour are P and V respctively. It is compressed isothermally there by volume becomes V/2, the final pressure will be

  • Question 2
    4 / -1

    If the intermolecular forces vanish away, the volume occupied by the molecules contained in 4.5 kg water at standard temperature and pressure will be

  • Question 3
    4 / -1

    A horizontal uniform glass tube of 100 cm, length sealed at both ends contain 10 cm mercury column in the middle. The temperature and pressure of air on either side of mercury column are respectively. 81°C and 76 cm of mercury. If the air column at one end is kept at 0°C and the other end at 273°C, the pressure of air which is at 0°C is (in cm of Hg)

  • Question 4
    4 / -1

    The diameter of oxygen atom is 3Å. The fraction of molecular volume to the actual volume occupied by oxygen at STP is

  • Question 5
    4 / -1

    The temperature of 5 moles of a gas which was held at constant volume was changed from 100°C to 120°C. The change in internal energy was found to be 80 Joules. The total heat capacity of the gas at constantvolume will be equal to

  • Question 6
    4 / -1

    The temperature of which the r.m.s speed of hydrogen molecules is equal to escape velocity on earth surface, will be

  • Question 7
    4 / -1

    Inside a cylinder having insulating walls and closed at ends is a movable piston, which divides the cylinder into two compartments. On one side of the piston is amass m of a gas and on the other side a mass 2 m of the same gas. What fraction of volume of the cylinder will be occupied by the larger mass of the gas when the piston is in equilibrium? Consider that the movable piston is conducting, so that the temperature is the same throughout

  • Question 8
    4 / -1

    The diameter of oxygen molecule is 2.94 × 10–10m. The van der Waal\'s gas constant ‘b\' in m3/mol will be

  • Question 9
    4 / -1

    The temperature of the mixture of one mole of helium and one mole of hydrogen is increased from 0°C to 100°C at constant pressure. The amount of heat delivered will be

  • Question 10
    4 / -1

    A vessel contains a mixture of one mole of oxygen and two moles of nitrogen at 300 K. The ratio of the average rotational kinetic energy per O2 molecule to that per N2molecule is
