Question

If the volume occupied by a gas at 337K and 10 atm is 1 litre, it'll occupy litres, if the pressure is reduced to 1 atm, temperature being same.

• A. 0.1
• B. 1
• C. 10
• D. 100

Answer 1

The correct option is C 10

As the temperature is constant, we will apply Boyle's law, which states that -
$PV$ = constant
Thus, $P_1{V}_1=P_2{V}_2$

where $P_{1}and{V}_1$ are the initial pressure and volume, and $P_{2}and{V}_2$ are the final pressure and volume of the gas.

Thus, $V_2=\frac{P_1{V}_1}{P_2}$

Hence, $V_2=\frac{10X1}{1}$
= 10 litres.
