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?

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)

see earlier

d₁ = displacement of tern from arctic to antarctic = 11000 miles

d₂ = displacement of tern from antarctic to arctic =   - 11000 miles

d = total displacement for the journey

total displacement for the journey is given as

d = d₁ + d₂

d = 11000 + (-11000)

d = 0 miles

t₁ = time of travel from arctic to antarctic = 3 months = 3 x 30 days = 90 days

t₂ = time of travel from antarctic to arctic = 3 months = 3 x 30 days = 90 days

t = total time of travel

total time of travel is given as

t = t₁ + t₂

t = 90 + 90

t = 180 days

average velocity is given as

average velocity = total displacement/ total time

v = d/t

v = 0/180

v = 0 miles/day
