For a gas, temperature and pressure are directly proportional. When you keep everything else constant, as the temperature of a gas goes up, its pressure goes up. As the temperature of a gas goes down, its pressure goes down. Gay-Lussac’s Law says that when the volume and amount of gas is constant, pressure and temperature are directly proportional. P ∝ T You can write this mathematically as P = kT
For a gas, temperature and pressure are directly proportional. When you keep everything else constant, as the temperature of a gas goes up, its pressure goes up. As the temperature of a gas goes down, its pressure goes down.
Gay-Lussac’s Law says that when the volume and amount of gas is constant, pressure and temperature are directly proportional.
You can write this mathematically as
P ∝ T or P = kT, where k is a proportionality constant
