A sample of an ideal gas occupies a volume of 'V' at a pressure 'P' and absolute temperature 'T'. The mass of each molecule is 'm'. The equation for density is 

An electric heater kept in vacuum is heated continuously by passing an electric current. Its temperature

A liquid used as a coolant in automobile engine is 

The air density at Mount Everest is less than that at the sea level. It is found by mountaineers that for one trip lasting a few hours, the extra oxygen needed by them corresponds to 30,000cc at sea level (pressure 1 atmosphere, temperature 27$$^o$$C). Assume that the temperature around Mount Everest is -$$73^o$$C and that the oxygen cylinder has a capacity of 5.2 litters. The pressure at which oxygen be filled (at site) in the cylinder is

A vessel contains air at a temperature of $$15^{0}C$$ and 60% R.H. What will be the R.H if it is heated to $$20^{0}C$$? (S.V.P at $$15^{0}C$$ is 12.67 & at $$20^{0}C$$ is 17.36mm of Hg respectively)

Final volume of the system will be nearly -

A vessel has 6g of hydrogen at pressure P and temperature 500K. A small hole is made in it so that hydrogen leaks out. How much hydrogen leaks out if the final pressure is $$P/2$$ and temperature falls to 300K?

A graph is plotted with PV/T on y-axis and mass of the gas along x-axis for different gases. The graph is 

If pressure of a gas contained in a closed vessel is increased by 0.4% when heated by $$1^{0}C$$, the initial temperature must be 

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