Volume occupied by one mole of gas at critical temperature and pressure

Minimum pressure required to liquify the gas at critical temperature.

[lyte id=”ZhP5npH9IcI” \]

Points to Remember:

The combination of critical temperature and critical pressure is called the critical point of a substance.

[…]

Temperature above which gas cannot be liquefied by pressure alone.

[lyte id=”OV0cDrEAE0k” \]

Points to Remember:

Gases can be converted to liquids by compressing the gas at a suitable temperature. The critical temperature of a […]

Gas which obeys gas laws and gas equation pV=nRT at all temperatures and pressures.

[lyte id=”otZvnZRQ65Y” \]

Base Concepts:

Ideal Gas Law

Points to Remember For a gas to be called as ideal gas it must […]

Rate of diffusion of gases is inversely proportional to the square root of their densities under similar conditions.

[lyte id=”JOOJ3MyHogE” \]

Points to Remember

Graham’s Law of diffusion can also be stated as the […]

Pressure of mixture of non-reacting gases is equal to sum of their partial pressures under similar conditions.

[lyte id=”RqffPYOoxd8″ \]

Points to Remember

The partial pressure of each gas is equal to the mole fraction […]

Volume of gas is directly proportional to temperature at constant pressure.

[lyte id=”MNNJwfWMUf0″ \]

At constant pressure,

V1/T1 = V2/T2

where T1 refers to the temperature of gas-1 and T2 refers to temperature of gas-2, V1 […]

Volume of gas is inversely proportional to pressure at constant temperature.

[lyte id=”3o7XNAPpUKg” \]

When mass and temperature is kept constant,

P1 V1 = P2V2

where P1 refers to the pressure of gas-1 and P2 […]
