A gas is heated from 0°C to 100°C at 1.0 atm pressure. If the initial volume of the gas is 10 litre, its final volume would be:
A vessel has nitrogen gas and water vapours at a total pressure of 1 atm. The partial pressure of water vapours is 0.3 atm. The contents of this vessel are transferred to another vessel having one third of the capacity of original volume, completely at the same temperature, the total pressure of the system in the new vessel is:
KE of one mole of He at 0°C is:
The pressure of a gas is due to
Equal masses of nitrogen and ethylene are mixed in an empty container at 27°C. The total pressure exerted by the gaseous mixture is 1 atm. The partial pressure exerted by ethylene gas is:
The ratio of velocities of diffusion of two gases A and B is 1 : 4. If the ratio of their masses in the mixture is 2 : 3; the ratio of their mole fraction is
2 moles each of hydrogen and oxygen are filled in a balloon and a small hole is pierced. After one hour 0.4 moles of oxygen effused out. The mole fraction of hydrogen in the ballon is;
A mixture of hydrogen and oxygen is 3 : 1 volume ratio is allowed to diffuse through a porous partition. What should be the composition of the initial gas diffusing out of the vessel.
An unspecified quantity of an ideal gas has a volume of 30 litre at 20°C. The gas is first compressed at 20°C until the pressure has doubled and then the temperature is raised to 100°C, while pressure is kept constant. Determine the final volume of the gas?
Two containers A and B contain the same gas. If the pressure, volume and temperature of the gas in A are two times as compared to that of B, and if the mass of the gas B is x gm, the mass of the gas in A will be;
The volume of average adult lung when expanded is about 6 litres at 98.4°F, if the pressure of oxygen is inhaled air is 168 mm of Hg. What will be the mass of oxygen required to occupy the lung at 98.4°F.
4.0 g of argon (at. Mass = 40) in a bulb at a temperature of T K had a pressure P atm. When the bulb was placed in hotter bath at a temperature 50° more than the first one, 0.8 g of gas had to be removed to get the original pressure. T is equal to
An L.P.G. cylinder contains 15 kg of butane gas at 27°C and 10 atmospheric pressure. It was leaking and its pressure fell down to 8 atmospheric pressure after one day. The gas leaked in 5 days is
