Kinetic Theory ...

The volume of a gas at $$27^o$$C and 2 atmospheric pressure is 2 litres. If the pressure is doubled and absolute temperature is made half, the new volume of gas is

A closed vessesl contains 8 gms of oxygen and 7gm of Nitrogen. Total pressure at a certain temperature is 10 atm. When all the oxygen is removed from the system without chage in temperature then the pressure will be

The volume occupied by 8 gm of oxygen at S.T.P. is

An air bubble rises from bottom to top of a liquid of density 1.5 g/cm$$^{3}$$. If its volume is doubled, the depth of liquids is

If pressure of an ideal gas contains in a closed vessel is increased by 0.5% the increase in temperature is 20k the initial temperature of the gas is

Two closed vessels of the equal volume contain air at 105kPa at 300K and are connected through a narrow tube. If one of the vessels is now maintained at 300K and the other at 400K then the pressure becomes.

At the top of a mountain a thermo meter read 7$$^{0}$$ C and barometer reads 70 cm of Hg. At the bottom of the mountain the barometer reads 76cm of Hg and thermometer reads 27$$^{0}$$ C. The density of air at the top of mountains is ______ times the density at the bottom.

At a given temperature and pressure 64 gm of Oxygen and X gm of H$$_{2}$$ occupy the same volume. Then x= ......gm

A one litre sphere and a two litre sphere are connected with a capillary tube of negligible volume. They contain an ideal gas at 27$$^{0}$$C at a pressure of 100cm of Hg. Keeping the temperature of one litre sphere constant at 27$$^{0}$$C, if temperature of two litre sphere is increased to 127$$^{0}$$C, then the final pressure is

At the bottom of a lake where the temperature is $${7}^{0}\,C$$ the pressure is $$2.8$$ atmosphere. An air bubble of radius $$1\, cm$$ at the bottom rises to the surface. Where the temperature is $${27}^{0}\, C$$. The radius of the air bubble at the surface is
