BOYLE'S LAW

Boyle's Law states that the volume of a gas is inversely proportional to its pressure, assuming constant temperature. This means that if you increase the pressure on a gas, its volume will decrease proportionally, and vice versa.

Example: If you have a balloon filled with air at a pressure of 1 atm and a volume of 1 L, and you increase the pressure to 2 atm, the volume will decrease to 0.5 L.

CHARLES'S LAW

Charles's Law states that the volume of a gas is directly proportional to its absolute temperature, assuming constant pressure. This means that if you increase the temperature of a gas, its volume will increase proportionally, and vice versa.

Example: If you have a balloon filled with air at a temperature of 273 K (0°C) and a volume of 1 L, and you increase the temperature to 373 K (100°C), the volume will increase to 1.37 L.

GAY LUSSAC'S LAW

According to Joseph - Louis Gay Lussac's law for gases, when the volume of gas is held constant, the pressure is directly proportional to its temperature. Or when the pressure increases, the temperature also increases and vice versa.

Example: The pressure of a gas in a cylinder when it is heated to a temperature of 250K is 1.5 atm. The initial temperature of the gas is 166.66 Kelvin if its initial pressure was 1 atm.

AVOGADRO'S LAW

Avogadro's law states that "equal volumes of all gases, at the same temperature and pressure, have the same number of molecules." For a given mass of an ideal gas, the volume and amount (moles) of the gas are directly proportional if the temperature and pressure are constant.

Example: Two moles of helium gas fill up an empty balloon to a volume of 2.5 L. The volume of the balloon would be 4.375 L if an additional 1.5 moles of helium gas is added at constant temperature and pressure.

IDEAL GAS LAW

Ideal Gas Law is an equation that states an ideal gas that relates pressure, volume, quantity of gas, and the absolute temperature. This ideal gas law or also called as "general gas equation," is simply the combination of all Simple Gas Laws including the Boyle’s Law, Charle’s Law, and Avogadro’s Law.

Example: The temperature, at which 0.654 moles of neon gas occupies 12.30 litres at 1.95 atmospheres, is 447 Kelvin.

COMBINED GAS LAW

The Combined Gas law is also a combination of Boyle’s, Charle’s, and Gay-Lussac’s Law into a single equation that is used to examine the behavior of constant amounts of gas when three gas conditions are changed. This combined gas law can be expressed as an expression

Example: 450 mL of a gas occupies a container that has a temperature of 28°C and a pressure of 788 mmHg. The temperature is at 32 Kelvin if the volume is reduced to 50 mL at 760 mmHg.
