Unit 5 Flashcards
S.T.P.
Standart temperature and pressure. T= 273K (0C)
P= 101.3kpa
S.T.A.P.
Standart ambient temperature and pressure. T=298K (25C) P=100 kpa
Kelvins
0K is the lowest possible temperature. Add 273 when in C to get to K
Charles law
v1/t1= v2/t2
Boyles law
p1v1=p2v2
Gay- Lussacs law
p1/t1=p2/t2
Combine gass law
p1v1/t1=p2v2/t2
Ideal gas law
pv=nRT
Universal gas constant
8.314
Law of combining volumes
volumes are directly proportional to a balanced chemical equation
Avagadros law
The volume of a gas is directly proportional to the number of mols of the gas
Daltons law of partial pressures
ptotal= p1+p2+p3+…..
Atmosphere
78% N2, 20%O2 and 2% other gasses
KMTG
Kinetic Molecular theory of gasses
1) Gas molecules move in straight lines
2) There is no loss of speed when they collide
3) The higher the temperature the faster the particles
Gasses
Particles are always in rapid movement
There is lots of space between particles
Shaped by the shape of their container
Can’t hold a charge
Diffuse when they more from high to low pressure
