A certain sample of gas has a volume of 0.2 litres measured at 1 atm pressure and 0^oC. At the same pressure but at 273^oC, its volume will be:

The rate of diffusion of a gas having molecular weight just double of nitrogen gas is 56 ml per sec. The rate of diffusion of nitrogen gas will be:

The volume of a gas is 100 ml at 100^∘C . If the pressure is kept constant, at what temperature will the gas have a volume of 200ml?

At what temperature in the Celsius scale, V(volume) of a certain mass of gas at 27⁰C will doubled keeping the pressure constant? 

A sample of O_2​ gas is collected over water at 23^oC at a barometric pressure of 751mm Hg (vapour pressure of water at 23^oC is 21mm Hg). The partial pressure of O₂​ gas in the sample collected is:

One litre of a gas weights 2g at 300 K and 1 atm. pressure. If the pressure is made 0.75 atm, at which temperature will one litre of the same gas weigh 1g

At 0^∘C and one atm pressure, a gas occupies 100 cc. If the pressure is increased to one and a half time and temperature is increased by one-third of absolute temperature, then final volume of the gas will be :

A gas of volume 100 cc is kept in a vessel at pressure 10.4 Pa maintained at temperature 24^∘C. Now, if the pressure is increased to 105 Pa, keeping the temperature constant, then the volume of the gas becomes:

The temperature at which RMS velocity of SO₂​ molecules is half that of helium molecules at 300K is:

The volume of 1 g each of methane (CH₄​), ethane (C₂​H₆​), propane (C₃​H₈​) and butane (C₄​H₁₀​) was measured at 350 K and 1 atm. What is the volume of butane ?
