Question

The volume of a gas at ${200}^{\circ }C$ is 200 ml. If the temperature is reduced to $-{20}^{\circ }C$ at constant pressure, its volume will be

• A. 172.6 ml
• B. 17.26 ml
• C. 192.7 ml
• D. 19.27 ml

Answer 1

The correct option is A

172.6 ml

$\frac{V_1}{T_1}=\frac{V_2}{T_2}\Rightarrow \frac{200}{293}=\frac{V_2}{253}\Rightarrow V_2=\frac{200\times 253}{293}=172.6ml$
