Pressure Flashcards
1
Q
how does a barometer work?
A
atmospheric p and gas p equalize when the atmospheric p pushes down on the dish w Hg, making a difference in metal lvls
2
Q
how does a manometer work
A
U-shaped tube with atm p pushing or gas p pushing to equalize Hg
3
Q
converting between units in P
A
760 mmHg = 760 torr = 1 atm = 101.3kPa = 10(^5) Pa
4
Q
Dalton’s Law of partial P
A
Ptotal = Pa + Pb + Pc (of each gas)
5
Q
how to find Pa with mol #
A
Pa = na / nt • Ptotal
6
Q
relationship of # moles and P
A
directly proportional
7
Q
relationship of Xa with P
A
Xa = Pa/Ptotal
