Question

The following plots represent Boyle's law of an ideal gas. Select the curve where the gas is at a temperature lower than the rest.

• A.
• B.
• C.

Answer 1

The correct option is A

Boyle's law states that when the temperature of a gas is kept constant, the volume of a fixed mass of gas is inversely proportional to its pressure.

$\text{P}\propto \frac{1}{\text{V}}$ or $\text{PV}=$ constant

For different temperatures, the curves of $\text{V}$ vs $\text{P}$ would look like as follows, with the curve corresponding to the highest temperature appearing the closest to the origin.
