The air density at Mount Everest is less than that at the sea level. It is found by mountaineers that for one trip lasting a few hours, the extra oxygen needed by them corresponds to 30,000cc at sea level (pressure 1 atmosphere, temperature 27$$^o$$C). Assume that the temperature around Mount Everest is -$$73^o$$C and that the oxygen cylinder has a capacity of 5.2 litters. The pressure at which oxygen be filled (at site) in the cylinder is

Which of the following assumptions is/are true according to kinetic theory?

The top surface of a liquid behaves like stretched membrane because

Helium gas is filled in a closed vessel (having negligible thermal expansion coefficient). When it is heated from 300 K to 600 K, then average kinetic energy of helium atom will be :

A gas mixture consists of 2moles of oxygen and 4moles of Ar at temperature T. Neglecting all vibrational modes, the total internal energy of the system is

Choose the correct answer from the given options below.

A sample of an ideal gas occupies a volume of 'V' at a pressure 'P' and absolute temperature 'T'. The mass of each molecule is 'm'. The equation for density is 

If 2 mole of an ideal monatomic gas at temperature $$T_{0}$$ is mixed with 4 moles of another ideal monatomic gas at temperature $$2T_{0}$$, then the temperature of the mixture is
