Question

If 300 ml of a gas at is cooled to $7 ^ { \circ } C$ at constant pressure, its final volume will be

• A. 135 ml
• B. 540 ml
• C. 350 ml
• D. 280 ml

Answer 1

Answer: (D)

280 ml

Answer 2

$\frac { V _ { 1 } } { T _ { 1 } } = \frac { V _ { 2 } } { T _ { 2 } }$ i.e. $\frac { 300 } { 300 K } = \frac { V _ { 2 } } { 280 K }$

V₂ = 280 ml
