Question

what is charles law?
the volume of a gas is directly proportional to its temperature when the pressure and the amount of gas are held constant
the pressure of a gas is directly proportional to its temperature when the volume and the amount of gas are held constant
the volume of a gas is inversely proportional to its temperature when the pressure and the amount of gas are held constant
the temperature of a gas is directly proportional to its pressure when the volume and the amount of gas are held constant
the amount of a gas is directly proportional to its temperature when the pressure and the volume of gas are held constant

Explanation:

Charles' Law is a gas law. It specifically relates the volume and temperature of a gas. When the pressure and the amount of gas (moles) are kept constant, the relationship is considered. The law states a direct - proportional relationship. That is, as the temperature of the gas increases, its volume increases and vice - versa.

Answer:

The volume of a gas is directly proportional to its temperature when the pressure and the amount of gas are held constant.
