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

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 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

During an experiment an ideal gas is found to obey an additional law V$$^{2}$$P= constant. The gas is initially at a temperature T and volume V. When it expands to a volume 2V, the temperature becomes

Two gases A and B having same pressure P, volume V and temperature T are mixed. if the mixture has volume and temperature as V and T respectively the pressure of mixture is

A vessel is filled with an ideal gas at a pressure of 200 atm and is at a temperature of 27$$^{0}$$ C. One half of the mass of the gas is removed from the vessel and the temperature of the remaining gas is increased to 87$$^{0}$$ C. At this temperature,the pressure of the gas will be

A gas is heated through $$1^{o}\ C$$ in a closed vessel. Its pressure is increased by $$0.4$$%. The initial emperature of the gas is

A given amount of a gas is heated till the volume and pressure both increase by $$2\%$$ each the percentage change in temperature of the gas is  equal to nearly
