Question

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,
$V_t=V_o(1+\frac{t}{273})$
Here, $V_o=$ Volume at $0^{\circ }C$ and $V_t=$ Volume at $t^{\circ }C$

$V_t=V_o(1+\alpha t)$
$\alpha =\frac{1}{273}=$ Coefficient of volume expansion
