Which statement is a description of boyle’s law

D. The volume and the pressure of a gas are inversely proportional when temperature is constant.

Explanation:

Boyle's law states that the pressure (P) of a given mass of a gas at constant temperature (T) is inversely proportional to its volume (V). Mathematically,

P= k/V where P is the pressure

K is the constant of proportionality

V is the volume

From the formula, PV = k

This means we can have more than one value of pressure and volume that is the equation can be written as;

P1V1 = P2V2 = k

Where P1 and P2 are initial and final pressure respectively

V1 and V2 are the initial and final volume respectively.

Note that inverse proportionality means that as the volume increases, the pressure decreases and as the volume decreases the pressure increases.
