Question

At constant pressure, the volume of a fixed mass of a gas varies as a function on temperature as shown in the graph

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

• A. 3
• B. 4
• C. 1
• D. 2

Answer 1

Answer: (D)

Volume of gas at $0^{\circ} C$
$V_{1}=250 \,cm ^{3}$
Volume of gas at $300^{\circ} C$
$V_{2}=500 \,cm ^{3}$
$ \therefore \frac{V_{2}}{V_{1}}=\frac{500}{250}=2$
Thus, the volume of the gas at $300^{\circ} C$ is larger than that at $0^{\circ} C$ by a factor of $2$ .
