Question

which of the following equations represents gay - lussacs law?
$p_{1}p_{2}=t_{1}t_{2}$
$\frac{p_{1}}{t_{1}}=\frac{p_{2}}{t_{2}}$
$p_{1}t_{1}=p_{2}t_{2}$

Explanation:

Gay-Lussac's Law states that for a fixed amount of gas at constant volume, pressure is directly proportional to absolute temperature. This proportionality means the ratio of pressure to temperature remains constant, so $\frac{P_1}{T_1} = \frac{P_2}{T_2}$.

Answer:

$\frac{P_1}{T_1} = \frac{P_2}{T_2}$
