Explanation

• Charles' Law states that the volume of a fixed amount of gas is directly proportional to its absolute temperature when pressure remains constant.
• The formula is V1 / T1 = V2 / T2, where temperature is measured in Kelvin.
• When the temperature increases, the gas volume increases; when the temperature decreases, the volume decreases, provided the pressure remains constant.
