Question 5

why does diffusion happen

Answer 5

diffusion happens because particles move about randomly.

Question 6

why does diffusion happen more quickly in gasses than in liquids ?

Answer 6

because gas particles move more freely than liquid particles

Question 7

how can the rate of diffusion be affected

Answer 7

Temperature concentration and size of particle

Question 7

how can the rate of diffusion be affected

Answer 7

Temperature concentration and size of particle

Question 8

what is brownian motiom and how is it caused

Answer 8

brownian motion was discovered when you can see pollen n grains and dust moving about randomly. it is caused when timny particles bump into things

Question 9

how is gas pressure made

Answer 9

when gas particles are contained in small spaces and bump into the walls

Question 10

why does gas pressure become more intense wand faster when heat is added

Answer 10

Because heat gives the particles energy which makes them move faster which applies more pressure
