Answer:
\frac {P_{1}V_{1}}{T_{1}}=\frac {P_{2}V_{2}}{T_{2}}
Explanation:
Gay-Lussac's law states that at constant volume, the pressure of a gas is directly proportional to the absolute temperature, P ∝ T at constant V. These three gas laws can be combined into a so-called combined gas law, P 1 V 1 T 1 = P 2 V 2 T 2.
