At constant temperature, when the volume of a gas is decreased, its pressure increases. This relationship is described by Boyle's Law , which states that for a given amount of gas at constant temperature, the pressure and volume are inversely proportional:
P×V=constantP\times V=\text{constant}P×V=constant
So, if volume VVV decreases, pressure PPP must increase to keep the product P×VP\times VP×V constant.
In summary:
- Volume ↓ → Pressure ↑ (at constant temperature)
