Question

At constant pressure, 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${}^{\circ }$C is larger than that at 0${}^{\circ }$C by a factor of

• A. 3
• B. 4
• C. 1
• D. 2

Answer 1

The correct option is D

2

From graph.:

T${}_1$ = 0${}^{\circ }$C V${}_1$= 250
T${}_2$ = 300${}^{\circ }$ V${}_2$ = 500
$\frac{V_2}{V_1}=2$
