Gas Laws

According to Gay-Lussac's law:

• pressure is inversely proportional to volume at constant temperature
• pressure is directly proportional to temperature at a constant volume
• volume is dierectly proportional to temperature at constant pressure
• volume is inversely proportional to temperature at constant pressure

Boyle's Law states that the volume of a gas is inversely proportional to its pressure if the

• temperature and number of particles are constant
• temperature reaches absolute zero
• number of particles decreases
• temperature and number of particles are doubled

The law that states that the volume of a gas is directly proportional to its temperature in kelvins if the pressure and the number of particles is constant.

• Dalton's law of partial pressures
• Charles' law
• Boyle's law
