How will the rms speed and the total kinetic energy of the gas molecules change, if its absolute temperature is decreased 4 times?

IF the number of gas molecules in a container in doubled, how will the pressure and the total kinetic energy of the gas molecules of that container change?

At which temperature does the kinetic energy of gas molecules become zero?

If the average kinetic energy of the molecules of a certain mass of a gas decreases, then

How will the momentum of a body change if its kinetic energy is doubled ?

How will the kinetic energy of the body change if its momentum in doubled ?

Calculate the kinetic energy of per gm molecule of He gas at 27^@C .

At a constant temperature, a vessel of 1 litre capacity contains 10^(23)N_(2) molecules. If the rms velocity of the molecules be 10^(3)m//s , then determine the total kinetic energy of the molecules and the temperature of the gas.

"The total kinetic energy of the molecules in an ideal gas with a volume V at pressure P and temperature T is equal to the total kinetic energy of the molecules present in the same volume of another ideal gas at the same pressure and at temperature 2T"-Justify the statement.

How does the volume of a definite mass of gas change with its absolute temperature at constant pressure?
