Question 5

What happens when a material is heated?

Answer 5

The intermolecular forces of attraction get weaker

Question 6

Boiling properties

Answer 6

• Bubble
• Temperature remains constant
• Faster
• All particles engaged

Question 7

Evaporation properties

Answer 7

• Slower
• Surface is only heated
• Happens naturally
• Occurs at any temperature
• No bubbles
• Temperature can flunctuate (vary)

Question 8

What is sublimation?

Answer 8

Solid turns straight to gas

Question 9

What is deposition?

Answer 9

Gas straight to solid

Question 10

What happens to a solid when it is melting?

Answer 10

It stays at the same temperature, because the energy is weakening the intermolecular forces of attraction.

Question 11

What is a mixture?

Answer 11

two or more different substances, not chemically joined together.

Question 12

What is filtration?

Answer 12

Used to separate a micture of insoluble solid and a liquid

Question 13

Whats distillation?

Answer 13

Separate out the solvent from a solution

Question 14

Whats crystallisation?

Answer 14

Separte a solute from a solution

Question 15

Whats chromotography?

Answer 15

Separate mixtures according to solutbility

Question 16

What is density?

Answer 16

is a measure of how much mass has been packed into a given volume (how heavy in grams or kg in 1 unit volume)

Question 17

What is the formula to find the density (units)?

Answer 17

Density (kg²/m³) = mass(kg) / volume (metres³)
