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

A given amount of gas is heated until both its pressure and volume are doubled. If initial temperature is 27$$^{0}$$ C, its final temperature is

One litre of helium under a pressure of 2 atm and at 27$$^{0}$$C is heated until its pressure and volume are doubled. The final temperature attained by the gas is

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 cylinder contains gas at a pressure of 2.5 atm. Due to leakage, the pressure falls to 2 atm, after sometime. The percentage of the gas which is leaked out is

The diagram shows the graphs of pressure vs density for a given mass of an ideal gas at two temperatures T$$_{1}$$ and T$$_{2}$$ :

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

If $$\rho $$ is the density, m is the mass of 1 molecule and K is the Boltzman constant for a gas then the pressure of the gas is:

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

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.
