The kinetic theory of gases predicts that the total kinetic energy of gaseous assembly depends on

Gases deviate from ideal behaviour because their molecules

The following question consists of an Assertion (A) and a Reason (R). Use the following options to mark the appropriate answer.

(A): The pressure of a fixed amount of an ideal gas is proportional to its temperature at constant volume.
(R): Ideal gas molecules neither attract nor repel each other.

The following question consists of an Assertion (A) and a Reason (R). Use the following options to mark the appropriate answer.

(A): SO₂ gas is easily liquefied while H₂ is not.
(R): SO₂ has a high critical temperature, while H₂ has a low critical temperature.

When a compressed real gas is allowed to expand through a porous plug at a temperature above its inversion temperature, there is
