    Study Notes

    Charles' Law

    • At constant pressure, the volume of a given mass of gas varies directly with its absolute temperature.
    • Joseph Gay-Lussac confirmed Charles' Law by experiments, showing that the volume of a gas at constant pressure increases linearly with its temperature.
    • When the temperature of a gas is increased, its volume also increases.
    • If the pressure of a gas remains constant and its temperature is decreased, its volume will decrease.
    • Charles' Law describes the relationship between the volume and temperature of a gas as directly proportional.
    • The relationship between the volume of a gas and its temperature according to Charles' Law is that the volume of a gas is directly proportional to its absolute temperature.
    • Absolute temperature must be used for the temperature measurement when applying Charles' Law.
    • If the temperature of a gas is given in degrees Celsius, it must be converted to Kelvin (absolute temperature) to apply Charles' Law.
    • The corresponding SI unit of volume when the volume of a gas is expressed in liters is cubic meters (m³).
    • According to Charles' Law, the volume of a gas increases if the temperature is increased.
    • The temperature scale that must be used while applying Charles' Law is the absolute temperature scale (Kelvin).
    • In a hot air balloon, when the air inside the parachute is heated, its volume increases.
    • When a basketball is left outside during winter, its volume decreases due to the decrease in temperature, as per Charles' Law.
    • The combustion process inside an automotive engine relates to Charles' Law, as the hot gases produced expand and increase the volume.
    • At absolute zero temperature, the volume of an ideal gas would be zero.
