Explanation:
1. Boyle's Law states that pressure is inversely proportional to the volume of the gas at constant temperature and number of moles.
[tex]P\propto \frac{1}{V}[/tex] (At constant temperature and number of moles)
[tex]P_1\times {V_1}=P_2\times V_2[/tex]
2. Charles' Law states that volume is directly proportional to the temperature of the gas at constant pressure and number of moles.
[tex]V\propto T[/tex] (At constant pressure and number of moles
[tex]\frac{V_1}{T_1}=\frac{V_2}{T_2}[/tex]
3. Gay Lussac's Law states that tempertaure is directly proportional to the pressure of the gas at constant volume and number of moles of gas
[tex]P\propto T[/tex] (At constant volume and number of moles)
[tex]\frac{V_1}{n_1}=\frac{V_2}{n_2}[/tex]
