Week 3 Topic: States of Matter – Read carefully, then use your notes answer the questions

1.     Diffusion and Osmosis are TWO processes used as proof for the particulate theory of matter.

a.      Define diffusion 

b.     Define osmosis 

c.      Identify TWO (2) real world examples of diffusion taking place. 

d.     Describe ONE (1) situation in which osmosis is taking place 

e.      What is the relation between diffusion and osmosis? (How are they similar; how are they different?) 

2.     Solids, liquids and gases are three states of matter which exist depending on the amount of movement energy the particles of matter have.

a.      What is movement energy called? Hint: it begins with k. 

b.     Aside from the energy of the particles, what is responsible for the existence of the three states of matter Hint: forces of… 

c.      How does the shape of a solid differ to that of a liquid? 

d.     Explain why gases are easy to compress but solids are harder to compress. Hint word: space 

e.      Explain why both liquids and gases have variable shape however the liquid has a definite volume while the gas has a variable volume. Hint: energy, space and forces of…
