Question

If gas has a volume of 500cm^3 when pressure ia 1000meters ia exerted on it what will be the volume if the pressure is changed to 150mm on the same temperature

Answer 1

The units of pressure are not mentioned clearly (pressure cannot be measured in meters or mm). The only reasonable assumption is that both P₁ and P₂ are measured in mmHg, a common unit of pressure. According to the Boyle's law,

$P_1V_1=P_2V_2$ ;

$V_2=\frac{P_1V_1}{P_2}=\frac{1000\ mmHg\times500\ cm^3}{150\ mmHg}=3333\ cm^3$

Answer: 3333 cm³
