Answer:
Boyle's Law: When the pressure of a gas increases, the volume of the gas will decrease as long as the temperature and amount of gas are constant.
So basically pressure is inversely proportional to Volume, when one increases, the other decreases, vice versa.
Equation:
Charles Law: When the temperature of a gas increases, the volume of a gas will also increase if the pressure and amount of gas are constant.
So basically Temperature and volume are directly proportional.
Equation:
Gay Lussac's Law: When the temperature of a gas increases, the pressure of a gas also increases when volume and the amount of gas remain constant.
Basically, Temperature and Pressure are directly proportional.
Equation:
Avogadro's Law: The most intuitive gas law. When you increase the amount of gas, the volume will also increase.
Meaning the moles (amount of gas) is directly proportional to volume.
Equation: (n stands for moles)
There is a combined gas law and ideal gas law but those are just the gas laws mentioned above but combined together. These should be everything.
