Question

At constant temperature, the volume of a fixed mass of a gas varies as a function of temperature as shown in the graph.
The volume of the gas at ${300}^{o}C$ is larger than that at $0^{o}C$ by a factor of

• A. $3$
• B. $4$
• C. $1$
• D. $2$

Answer 1

The correct option is D $2$

$T_1=0^{o}C{V}_1=250$
$T_2={300}^o{V}_2=500$
$\frac{V_2}{V_1}=2$

The volume of the gas at ${300}^{o}C$ is larger than that at $0^{o}C$ by a factor of 2.
