Question

Which gas law states that the pressure of a gas decreases when volume is increased and the temperature is unchanged

Answer 1

Boyle's law state that the total pressure of an enclosed gas is inversely proportional to the volume of the container, as long as the temperature is constant

Answer 2

Answer: Boyle's law

Explanation: It states that pressure of a gas is inversely proportional to the volume of a gas at constant temperature.

$P$∝$\frac{1}{V}$       at constant temperature

or If the pressure of gas is decreased, the volume increases if the temperature is unchanged and If the pressure of gas is increased, the volume decreases if the temperature is unchanged.

$P_1V_1=P_2V_2$
