Using the same sample of gas ( P 1 = 795 torr , T 1 = 25 ∘ C ), we wish to change the pressure to 7950 torr with no accompanying change in volume or amount of gas. What temperature T 2 , in Celsius, is needed to reach this pressure?
Homework Answers
Given:
Ti = 25.0 oC
= (25.0+273) K
= 298 K
Pi = 795 torr
Pf = 7950 torr
use:
Pi/Ti = Pf/Tf
795.0 torr / 298.0 K = 7950.0 torr / Tf
Tf = 2980 K
= (2980 - 273) oC
= 2707 oC
Answer: 2707 oC
