Question

A pressure P-absolute temperature T diagram was obtained when a given mass of gas was heated. During the heating process from the state 1 to state 2 the volume –

• A. Remained constant
• B. Decreased
• C. Increased
• D. Changed erratically

Answer 1

Answer: (C)

Increased

Answer 2

PV = µRT

̃ V µ (Q µ and R are fixed)

Since,T increases rapidly and P increases slowly thus volume of the gas increases.
