Question

Which of the following plots represent the Charles' law for an ideal gas?

• A.
• B.
• C.
• D.

Answer 1

The correct option is D

According to Charles' law, When the pressure of gas is kept constant, the volume of a gas is directly proportional to the temperature of the gas.

$\text{V}\propto \text{T}⟹\frac{\text{V}}{\text{T}}=$ constant

So, the plot of $\text{V}$ vs $\text{T}$ is a straight line passing through the origin, like $\text{y}=\text{mx}$ or $\frac{\text{y}}{\text{x}}=\text{m}$.
