Boyle's Law: \( P_1 V_1 = P_2 V_2 \) (Constant Temperature)
Charles's Law: \( \frac{V_1}{T_1} = \frac{V_2}{T_2} \) (Constant Pressure)
Gay-Lussac's Law: \( \frac{P_1}{T_1} = \frac{P_2}{T_2} \) (Constant Volume)
Avogadro's Law: \( \frac{V_1}{n_1} = \frac{V_2}{n_2} \) (Constant T and P)
Ideal Gas Equation: \( PV = nRT \)
