The temperature of a sample of gas in a steel

Snezhnost [94]

Answer:

$P_2=51.7kPa$

Explanation:

Hello,

In this case, we apply the Gay-Lussac's law which allows us to understand the pressure-temperature behavior via a directly proportional relationship:

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

Thus, since we are asked to compute the final pressure we solve for it in the previous formula, considering the temperature in absolute Kelvin units:

$P_2=\frac{P_1T_2}{T_1}=\frac{30.0kPa*(25.0+273)K}{(-100.0+273)K} \\\\P_2=51.7kPa$

Best regards.
