A gas occupies 340 mL at 273 K and 610 torr. What final temperature would be required to increase the pressure to 1 atm, the volume being held constant?

Question

Quizplus · Accepted Answer

Using the combined gas law:
(P1/T1) = (P2/T2)
Substituting the given values,
(610 torr/273 K) = (1 atm/T2)
T2 = (1 atm * 273 K) / (610 torr) = 367 K

Therefore, the final temperature required to increase the pressure to 1 atm is (367 K - 273 K) = 94 °C. Converting to Celsius, we get 67 °C (approximately). Hence, the best choice is A.
