What will be the temperature of the air in the container when the pressure is at 1000 mm Hg?

Question

A rigid metal container, with a volume of 3.0 L, is sealed outdoors when the barometric pressure is 750 mm of Hg and the air temperature is -3.0 degrees celsius. If the container is brought indoors and placed in front of a fire, what will be the temperature of the air in the container when the pressure is at 1000 mm of Hg?
(a) -4 degrees celsius
(b) 87 degrees celsius
(c) 269 degrees celsius
(d) 360 degrees celsius

Answer 1

P/T = p/t
t = pT/P = 1000*270/750 = 360(k)
(b) 87 degrees celsius
