Question

At a certain pressure, the volume occupied by a given mass of a gas is 10 $L$ at 0${}^o$C. Calculate the volume occupied by the gas at 91${}^o$C at the same pressure.

• A. 5.83 $L$
• B. 20.8 $L$
• C. 7.5 $L$
• D. 13.33 $L$

Answer 1

The correct option is D 13.33 $L$

Given that at $STP$, $V_1=10L$ and $T_1=273K$
$T_2$ = 91+273 = 364 $K$
Applying Charle's law; $\frac{V_1}{T_1}=\frac{V_2}{T_2}$
$V_2=\frac{10\times 364}{273}=13.33L$
