Final answer:
Boyle's law indicates that at constant temperature, when the volume of gas is doubled, its pressure decreases, displaying an inverse relationship between volume and pressure.
Step-by-step explanation:
According to Boyle's law, at a constant temperature, if the volume of a container of gas is doubled, the pressure of the gas will decrease. This is because Boyle's law states that volume and pressure have an inverse relationship. Therefore, if the volume doubles, the pressure must halve to maintain the equation P1V1 = P2V2, where P represents pressure and V represents volume. To illustrate, if a gas inside a 1-liter container exerts a certain pressure, when the volume is increased to 2 liters, the pressure exerted by the gas molecules against the container walls decreases, resulting in half the original pressure.
