Question

1. gay - lussac’s law

$\frac{p_1}{t_1}=\frac{p_2}{t_2}$ (solve for $t_1$)
$p_1$ = initial pressure
$t_1$ = initial absolute temperature
$p_2$ = final pressure
$t_2$ = final absolute temperature

Explanation:

Step1: Cross - multiply

$P_1T_2 = P_2T_1$

Step2: Solve for $T_1$

$T_1=\frac{P_1T_2}{P_2}$

Answer:

$T_1=\frac{P_1T_2}{P_2}$
