Kinetic Theory

Question 1

what are the 3 principles of kinetic theoyr

Answer 1

1. all matter is amde up of atoms
2. atoms are in constant motion
3. when atoms collide no energy is lost

Question 2

how are partices arranged in a solid

Answer 2

tightly packed, close togthether
no movement
definite shape and volume

Question 3

how are partices arranged in a liquid

Answer 3

close together but roll over each other

no def shape or volume

Question 4

how are partices arranged in a gas

Answer 4

very far apart
move very fast
no def shape or vlume

Question 5

describe the changes between S, L AND G

Answer 5

S melt L
L boil G
G condensate L
L freeze S

Question 6

Explain melting point

Answer 6

heat will increase KE of particles therefore they can break

Question 7

what are the 3 principles of the kinetic theory of gases

Answer 7

1. ke is the same for all gases at the same temo
2. collisions are elastic (dont lose speed/KE in collision)
3. collision relies on temp/amount and volume of gas
