(a) State Boyle’s law. - Leaving Cert Physics - Question a - 2017

Boyle’s law states that the pressure of a gas is inversely proportional to its volume when the temperature is held constant. This means that as the volume of a gas decreases, the pressure increases, and vice versa. Mathematically, this relationship can be expressed as:

$P imes V = k$

where:

• $P$ is the pressure of the gas,
• $V$ is the volume of the gas,
• $k$ is a constant for a given mass of gas at a specified temperature.
