Explanation:

Step1: Convert temperatures to Kelvin

$$T_1 = 25 + 273 = 298\ K$$
$$T_2 = 65 + 273 = 338\ K$$

Step2: Apply Gay - Lussac's Law ($\frac{P_1}{T_1}=\frac{P_2}{T_2}$)

$$P_2=\frac{P_1T_2}{T_1}$$
Substitute $P_1 = 2.63\ atm$, $T_1 = 298\ K$, $T_2 = 338\ K$
$$P_2=\frac{2.63\times338}{298}$$
$$P_2=\frac{888.94}{298}\approx2.98\ atm$$

Answer:

$2.98$
