Correct order of van der Waals constant b of given gases is

Match the following.

A gas at 300 K and 10 bar has molar volume 10% more than that for an ideal gas under the same conditions. The correct option about the gas and its compressibility factor (Z) is

For an ideal system at thermal equilibrium, the velocity distribution of the constituting particles

Which of the following gases can be liquefied most easily?

A gas at 300 K and 10 bar has molar volume 10% more than that for an ideal gas under the same conditions. The correct option about the gas and its compressibility factor (Z) is

Which of the following gases can be liquefied most easily?

A car tyre is filled with nitrogen gas at 35 psi at 27°C. It will burst if pressure exceeds 40 psi. The temperature in °C at which the car tyre will burst is--------------. (Rounded – off to the nearest integer)

A box contains 0.90g of liquid water in equilibrium with water vapour at 27°C. The equilibrium vapour pressure of water at 27°C is 32.0 Torr. When the volume of the box is increased, some of the liquid water evaporates to maintain the equilibrium pressure. If all the liquid water evaporates, then the volume of the box must be________ litre. [Nearest Integer]

(Given : R = 0.082 L atm K^-1 mole^-1)

(Ignore the volume of the liquid water and assume water vapours behave as an ideal gas.)

An evacuated glass vessel weights 40.0g when empty, 135.0g when filled with a liquid of density 0.95 g mL^-1 and 40.5 g when filled with an ideal gas at 0.82 atm at 250 K. The molar mass of the gas in g mo^-1 is:
