State Boyle's law. - Leaving Cert Chemistry - Question 0 - 2015

Boyle's Law states that the pressure of a given mass of gas is inversely proportional to its volume when the temperature is held constant. Mathematically, this can be expressed as:

$P V = k$

where:

• $P$ is the pressure of the gas,
• $V$ is the volume of the gas,
• $k$ is a constant specific to the gas under the given conditions.

This relationship means that as the volume increases, the pressure decreases, provided the temperature remains unchanged.
