Question

The coefficient of volume expansion of a gas is:

• A. $\frac{1}{273}$
• B. $\frac{2}{273}$
• C. $\frac{3}{273}$
• D. $\frac{4}{273}$

Answer 1

The correct option is A $\frac{1}{273}$

According to Charles' law $V_t=V_0(1+\frac{t}{273})$
$V_t=V_0(1+\alpha t)$ $\alpha =\frac{1}{273}=\text{Coefficent of volume expansion}$ Here, $V_0=\text{Volume at}0{}^{\circ }C$ and $V_t=\text{Volume at}t{}^{\circ }C$
