Gay-Lussac's Law
The Relationship Between Temperature and Pressure in Gases
Two key details to keep in mind when it comes to Gay-Lussac’s Law.
Direct Proportionality: When the temperature of a gas increases, its pressure increases, and when the temperature decreases, so does the pressure.
Gay-Lussac’s Law holds true only if the volume of the gas remains constant.
In gas laws, temperature is always measured in Kelvin because the Kelvin scale starts at absolute zero, ensuring accurate proportionality between temperature and pressure.
No, Gay-Lussac’s Law only applies when the volume of the gas is constant. If the volume changes, other gas laws, such as the Combined Gas Law, may be more appropriate.
