Kinetic Theory ...

A flask is filled with 13 gm of an ideal gas at 27$$^{0}$$C its temperature is raised to 52$$^{0}$$C . The mass of the gas that has to be released to maintain the temperature of the gas in the flask at 52$$^{0}$$C and the pressure remaining the same is

At what temperature will the hydrogen molecules escape from Earth's surface?

During an experiment an ideal gas is found to obey an additional gas law VT =constant. The gas is initially at temperature T and pressure P. When it is heated to the temperature 2T, the resulting pressure is

If the pressure of a gas contained in a closed vessel increases by x% when heated by 1$$^{0}$$C , its initial temperature is

The average kinetic energy of hydrogen molecule at NTP will be

The pressure of a certain mass of gas at 27$$^{0}$$C is 84cm of Hg. If 25% of the gas is now introduced into the same vessel at the same temperature, the final pressure of the gas will be in cm of Hg

A cycle tube has volume $$2000 cm^3$$. Initially the tube is filled to 3/4th of its volume by air at pressure of $$105 N/m^{2}$$. It is to be inflated to a pressure of $$6 \times 10^{5} N/m^{2}$$ under isothermal conditions. The number of strokes of pump, which gives $$500 cm^3$$ air in each stroke, to inflate the tube is

If the number of degrees of freedom of a gas is f, then the value of $$\gamma $$ will be

The total kinetic energy of $$8$$ litres of helium molecules at $$5 $$ atmosphere pressure will be

A uniform tube with piston in the middle and containing a gas at 0$$^{0}$$C is heated to 100$$^{0}$$C at one side . If the piston moves 5 cm, find the length of the tube containing the gas at 100$$^{0}$$C.
