The temperature of a 0.750-L gas sample at 25 °C and 2.00 atm is changed to 250 °C. What is the final pressure of the system,at constant volume?

Question

Quizplus · Accepted Answer

The final pressure can be calculated using the ideal gas law and the concept that $P_1/T_1 = P_2/T_2$ at constant volume, where temperatures are in Kelvin. Converting temperatures to Kelvin: $T_1 = 25 °C + 273 = 298 K$ and $T_2 = 250 °C + 273 = 523 K$. Solving for $P_2$, $P_2 = P_1 \times (T_2/T_1) = 2.00 atm \times (523 K / 298 K) = 3.51 atm$.
