chap 2 kpt (diffusion)

Question 1

diffusion

Answer 1

net movement of particles from a region of higher concentration to a region of lower concentration

Question 2

format of ans for porous pot qn, what will happen to the water level at X

Answer 2

1. calculate Mr
2. (which gas diffuses faster and why)
   ~ gas will diffuse into the porous pot faster than ~ gas will diffuse out of the porous pot because ~ has a smaller Mr than ~
3. total no. of gas molecules in the porous pot (increases/decreases)
4. the water level at x will move (downwards/upwards)

Question 3

what affects rate of diffusion

Answer 3

temp
mr

Question 4

what is kinetic particle theory

Answer 4

All matter is made up of tiny particles and these particles are in constant random motion
