Question

As the pressure of a gas decreases to half it's original value what happens to the volume of the gas if temperature is held constant

Answer 1

According to Boyle's law, when the pressure of a gas decreases to half its original value, and temperature is held constant, the volume of the gas will double. Boyle's law states that the pressure and volume of a gas are inversely proportional to each other, meaning that if one variable decreases, the other variable will increase proportionally.
