Question 6

Heat Energy

Answer 6

In order for a substance to change state it needs heat energy

Question 7

Latent heat

Answer 7

As a substance changes state it uses latent heat there is no change in temperature but the state of material changes

Question 8

The melting point

Answer 8

Is when both the solid state and liquid state exist together

Question 9

The boiling point

Answer 9

Is when is when evaporation happens throughout the liquid

Question 10

Condensation

Answer 10

Is the changing of gas to liquid

Question 11

Diffusion

Answer 11

Is the movement of particles from a high concentration to an area of low concentration eg spray perfume in one corner of the room and then in a while it will travel into the other

Question 12

Four state of matter plasma is the fourth state of matter like gas but can conduct electricity

Question 13

Mixture

Answer 13

A mixture contains two substances mingled together but not chemically combined

Question 14

There are four methods of separating mixtures

Answer 14

Filtration
Evaporation
Distillation
Chromatography

Question 15

Filtration

Answer 15

Used to separate small insoluble objects do not dissolve in a liquid
From liquid by using filtered paper and a funnel to separate

Question 16

Evaporation

Answer 16

Is used to separate soluble solids dissolve in liquids from a solution from evaporation
Of the liquids to leave the solids eg salt water.

Question 17

Physical change

Answer 17

No change in particles just change in the particle arrangement and energy example salt

Question 18

Chemical change

Answer 18

A chemical reaction takes place and a new substance is formed

Question 19

During the chemical reaction

Answer 19

The atoms rearrange to form a new substance might be seen i. Temperature or colour

Question 20

Law of conversation of mass

Answer 20

Matter van be changed from one to another

Question 21

Distillation

Answer 21

Used to separate two liquids with different boiling points such as alcohol boils at 78 degrees
And water boils at 100 degrees and also used to separate soluble liquids

Question 22

Chromatography

Answer 22

Used to separate a mixture of dissolved substances in a solution eg the different colours in a black marker
