A 20 L container hold 0.650 mol of He gas at `37^@C` at a pressure of 623.8 bar. What will be new pressure inside the container if the volume is reduced to 12L. The temperature is increased to `177^@C` and 1.25 mol of additional He gas was added to it?

If the pressure of a gas at constant volume changes from 2 atm to 1 atm. The temperature changes from 0^@C

Calculate the volume of 1 mol of a gas at exactly 20^@C at a pressure of 101.35 kPa .

The pressure of a gas in a closed vessel is increased by 0.4%, if the temperature of the gas is increased by 1^@C , the initial temperature of the gas is

The volume of a given mass of a gas at 0^@C is 2dm^3 Calculated the new volume of the gas at constant pressure when temperature increase by 10^@C

The volume of a given mass of a gas at 0^@C is 2 dm^3. Calculate the new volume of the gas at constant pressure when :The temperature is decreased by 10^@C.

At 25^@C and 760 mm of Hg pressure a gas occupies 600mL volume. What will be its pressure at the height where temperature is 10^@C and volume of the gas 640mL?

At pressure P and absolute temperature T a mass M of an ideal gas fills a closed container of volume V. An additional mass 2M of the same gas is added into the container and the volume is then reduced to V/3 and the temperature to T/3 . The pressure of the gas will now be:
