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

Q V₂ > V₁ $\left[ \frac { \mathrm { P } } { \mathrm { T } } \propto \frac { 1 } { \mathrm {~V} } \propto \tan \theta \right]$ \ (1) to (2) ­
