Final answer:
Charles's law states that the volume of a given amount of gas is directly proportional to its temperature on the Kelvin scale when the pressure is held constant.
Step-by-step explanation:
When it comes to the effect of increasing temperature on the volume of a gas, we can use Charles's law. Charles's law states that the volume of a given amount of gas is directly proportional to its temperature on the Kelvin scale when the pressure is held constant.
