Question

The correct statement about critical temperature is (a) It is different for different gases (b) same for all gases (c) it is greater than room temperature (d) all​

Answer 1

Answer:

critical temperature is different for different gases.

Explanation:

The critical temperature of a substance is the highest temperature at which the substance can exist as a liquid. At temperatures above the critical temperature, the substance can no longer be liquified regardless of the amount pressure applied to it. The critical temperature of a gas provides idea of the strength of the intermolecular forces of attraction that its particles are subject to. gaseous substance has low intermolecular forces and hence harder to liquify. That is gases with lower intermolecular forces have lower critical temperature. There for the correct statement is option a , different for different gases.

Answer 2

The correct option is a.

• The critical temperature of a gas is defined as the highest temperature at which the matter can exist as a liquid. Above critical temperatures matter converts to gas.
• The critical temperature of gas gives us an idea about the strength of the intermolecular forces of attraction of a substance.
• It is different for different gases.
• It is less than room temperature.
