Answer 1 :

Name : Boyle's law

Variables : Pressure, volume

Constants : Temperature, moles of gas

Equation : PV = k

Name : Charles’s law

Variables : Volume, temperature

Constants : Pressure, moles of gas

Equation : V = kT

Name : Gay-Lussac's law

Variables : Pressure, temperature

Constants : Volume, moles of gas

Equation : P = kT

Name : Combined gas law

Variables : Pressure, temperature, volume

Constants : Moles of gas

Equation :

Explanation :

Boyle's Law : It is defined as the pressure is inversely proportional to the volume of the gas at constant temperature and number of moles.

Charles' Law : It is defined as the volume is directly proportional to the temperature of the gas at constant pressure and number of moles.

Gay-Lussac's Law : It is defined as the pressure is directly proportional to the temperature of the gas at constant volume and number of moles.

Avogadro's Law : It is defined as the volume is directly proportional to the number of moles of the gas at constant pressure and temperature.

Combined gas law : It is the combination of above four laws.

It is represented as,

Answer 2 : The number of moles are assumed to be constant while using the combined gas law.
