If the temperature of 5L of a gas at atmo-spheric pressure is changed from 200K to 50K, what will be the volume?

If the absolute temperature of a gas is doubled and the pressure is reduced to one half, the volume of the gas will.

If the pressure of a certain amount of a gas is doubled keeping the temperature constant, what would be the volume of, the gas?

At constant temperature, the pressure of VmL of a dry gas was increased from 1 atm to '2 ~atm .' The new volume will be
