Boyle's law states that the volume of a fixed mass of gas is inversely proportional to it's pressure at a CONSTANT TEMPERATURE.

#### Explanation:

Suppose the volume of the gas is symbolized as $V$, pressure as $P$, temperature as $T$, $n$ is the number of moles of the gas.

So Boyle's law can be explained as,
$V$ is proportional to $\frac{1}{P}$ (inversely proportional) [$T , n$ are constant ]
$V = k$ $\text{x} \frac{1}{P}$ , $k$ is a proportionally constant.

$P V = k$ (cross multiplication)

So, it can be said that, " At a constant temperature, the product of multiplication of Pressure and Volume of a gas of fixed mass is always a constant."
