If the pressure of a given gas sample doubles, what happens to the volume of gas? (Assuming that the amount of gas and the temperature of the gas stay the same).

According to Boyle's Law, if the pressure of a fixed amount of gas at a constant temperature is increased, the volume of the gas will decrease in proportion. Mathematically, P1V1 = P2V2, where P1 and V1 are the initial pressure and volume, and P2 and V2 are the final pressure and volume. If the pressure is doubled (P2 = 2P1), then the volume must be halved (V2 = V1/2) to maintain the same amount of gas at the same temperature. Thus, the volume will decrease by a factor of 2.
