As volume increases, the pressure decreases since both are inversely proportional with respect to Boyle’s law.
Explanation:
An inverse proportionality exists between the volume and the pressure, this law will hold true if there are no changes in the molecules number and the temperature.
At an initial state of fixed quantity of gas, this law helps to determine changes in the pressure and volume. This law was introduced in the year 1662. According to this law, when the volume increases then the pressure in the contained gas would decrease. This is because of the reason that there exists an opposite relationship between the pressure and the volume.
