Question

As the pressure on a sample of gas increases, the volume of the sample _____. decreases stays the same increases

Answer 1

Answer : As the pressure on a sample of gas increases, the volume of the sample decreases.

Explanation :

According to the Boyle's, law, the pressure of the gas is inversely proportional to the volume of gas at constant temperature and moles of gas.

$P\propto \frac{1}{V}$     (At constant temperature and moles of gas)

From the we conclude that the higher the pressure of gas, lower will be the volume and lower the pressure of gas, higher will be the volume of gas.

Hence, as the pressure on a sample of gas increases, the volume of the sample decreases.

Answer 2

By Boyle's law the volume of the sample decreases, provided temperature is constant.
