NEET Physics Question - Thermal Physics

Assertion (A): A real gas behaves as an ideal gas at high temperature and low pressure.

Reason (R): At low pressure and high temperature intermolecular forces vanish away and volume of gas molecules is negligible.

Both (A) & (R) are true and the (R) is the correct explanation of the (A)

Both (A) & (R) are true but the (R) is not the correct explanation of the (A)

(A) is true but (R) is false

Both (A) and (R) are false

Solution:

Assertion (A) is true. Real gases approximate ideal gas behavior under conditions of high temperature (high kinetic energy overcomes intermolecular forces) and low pressure (molecules are far apart, making their own volume negligible).

Reason (R) accurately states these conditions as the underlying cause for ideal gas behavior. Thus, R is the correct explanation for A.
