Answer 2

1. Closely packed in a disorderly manner
2. Slide past each other freely throughout the liquid
3. Forces of attraction is less strong
4. Kinection energy of particles is low
5. Shape is indefinite
6. Volume is definite
7. Cannot be compressed

Question 3

Question 4

In a temperature graph, what does a horizontal line represent?

Answer 4

A state( liquid, solid, gas)

Question 5

What does the the sloping graph represent?

Answer 5

A change of state

Question 6

Sublimation

Answer 6

Sublimation is the process by which a solid changes directly into gas

Question 7

Vapour Deposition

Answer 7

Vapour deposition is when a gas particle are cooled until they slow down and arrange themselves into the solid state.
