According to Boyle's Law, if the pressure on a gas doubles at constant temperature, what happens to its volume?

Explanation:
In isothermal conditions, pressure and volume are inversely related for a fixed amount of gas (P·V = constant). If the pressure doubles while the temperature stays the same, the volume must adjust so that the product P·V remains unchanged. Since P2 = 2P1, V2 must be V1/2. So the volume becomes half. This is the direct consequence of the inverse P–V relationship in Boyle’s law.
