Question

An oxygen bottle containing a fixed volume of o2 gas has a pressure of 800.00 mm hg and a temperature of 295k. if the bottle is heated to 328k what will the pressure of o2 gas be within the bottle and which law will you use to solve it?

Answer 1

Since volume and number of moles are constant, we use the Gay-Lussacs Law to find the variable P2.

Gay-Lussacs law is expressed as:

P1 / T1 = P2 / T2

800 / 295 = P2 / 328

P2 = 889.50 mm Hg (ANSWER)
