Unit 5

Question 1

S.T.P.

Answer 1

Standart temperature and pressure. T= 273K (0C)

P= 101.3kpa

Question 2

S.T.A.P.

Answer 2

Standart ambient temperature and pressure. T=298K (25C) P=100 kpa

Question 3

Kelvins

Answer 3

0K is the lowest possible temperature. Add 273 when in C to get to K

Question 10

Law of combining volumes

Answer 10

volumes are directly proportional to a balanced chemical equation

Question 11

Avagadros law

Answer 11

The volume of a gas is directly proportional to the number of mols of the gas

Question 12

Answer 12

ptotal= p1+p2+p3+…..

Question 13

Atmosphere

Answer 13

78% N2, 20%O2 and 2% other gasses

Question 14

KMTG

Answer 14

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

Question 15

Gasses

Answer 15

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
