Answer:
See below
Explanation:
Use the combined gas law where:
P₁V₁ P₂V₂
------ = -------- You are looking for T₂.
T₁ T₂
You can either solve the equation above to T₂ now and then plug the number in or you can plug the numbers in now and solve. Do the latter.
(51)(1.0) (85)(2.1)
----------- = ------------
320 T₂
Cross-multiply and you get:
(51)T₂ = (85)(2.1)(320) or T₂ = (85)(2.1)(320) / 51
T₂ = 1120 K
