The gas laws describe the behavior of gases under specific conditions of temperature, pressure, and volume. Three gas laws show the relationship between two variables when all others are held constant: Boyle’s law (pressure and volume are inversely proportional), Charles’s law (volume and temperature are directly proportional), and Gay-Lussac’s law (temperature and pressure are directly proportional).

Question

What would happen to the pressure of a gas, if the temperature increases, while the volume is held constant?

Answer 1

According to Gay-Lussac's law, when the temperature of a gas increases while the volume is held constant, the pressure of the gas will also increase. This is because the temperature and pressure of a gas are directly proportional to each other when volume is constant. So, as the temperature increases, the gas molecules will move faster and collide with the walls of the container more frequently and with greater force, leading to an increase in pressure.
