The molar gas constant is the same for all gases because at the same temperature and pressure, equal volumes of gases have the same :
Assertion: PV/T=constant for 1 gram of gas. This constant varies from gas to gas.
Reason:1 gram of different gases at NTP occupy different volumes.
The critical temperature of the gas is the temperature:
A gas at temperature 270C and pressure 30 atmospheres is allowed to expand to one atmospheric pressure. If the volume becomes 10 times its initial volumes, the final temperature becomes :
Assertion:PV/T=constant for 1 mole of gas. This constant is same for all gases.
Reason:1 mole of different gases at NTP occupy same volume of 22.4 litres.
A cylinder contains a gas at temperature of 270C and a pressure 1MPa. If the temperature of the gas is lowered to -230 C , the change in pressure is
