Question 14

How does a substance change state

Answer 14

It needs heat energy

Question 15

What energy does a substance use when changing state

Answer 15

Latent heat (there is no change to temperature, but the state of the material changes.

Question 16

Melting point

Answer 16

Is when both the solid and liquid state exist together (changing from a solid to a liquid)

Question 17

Boiling point

Answer 17

Of a liquid is when evaporation begins to happen throughout the liquid (changing from a liquid to a gas)

Question 18

Condensation

Answer 18

Is the changing of a gas to a liquid

Answer 19

Evaporating

Condensing

Question 21

Solid to liquid

Answer 21

Melting

Question 22

Liquid to solid

Answer 22

Freezing

Question 23

Diffusion

Answer 23

Is the movement of particles from an area of high concentration to an area of low concentration E.g spray perfume in one corner of the room and it spread to the rest of the room

Question 24

(//////////———•••———/////////)

Answer 24

Please

Question 25

Plasma i

Answer 25

Is the fourth state of matter, like gas, but can conduct electricity.

Question 26

Physical change

Answer 26

No change in particles just the particle arrangement and energy easy to reverse E.g mixing water and salt

Question 27

Chemical change

Answer 27

A chemical reaction takes place and a anew substance is formed. Very difficult to reverse E.g. burning a match

Question 28

During a chemical reaction

Answer 28

The atoms rearrange to form a new substance. Might be seen by colour change, temperature change, light being emitted by bubbles.

Question 29

Law of conservation of mass

Answer 29

Matter can be changed from one form to another during physical and chemical changes there is no overall change in mass

Question 30

A mixture

Answer 30

Consists of two or more substances mingles together but not chemically combined E.g. sand and water

Question 31

There are four method of separating mixture

Answer 31

1: filtration 2: Evaporation 3: Distillation 4: chromatography

Question 32

Filtration

Answer 32

Used to separate small insoluble solids (do not dissolve in a liquid) from a liquid by using filter paper and a funnel to trap the solids E.g. sand and water

Question 33

Evaporation

Answer 33

Sued to separate soluble solids (dissolve in liquids) from a solution by evaporating off the liquid to leave the solids E..g salt

Question 34

Law of conservation of mass

Answer 34

Matter can be changed from one form to another. During physical and chemical changes, there is no overall change in mass.

Question 35

A mixture

Answer 35

Consists of two or more substances mingled together but no chemically combined

Question 36

Distillation

Answer 36

Used to superset two liquids with different boiling points such as alcohol (boils at 78 degrees ) and (water boils at 100 degrees) ? Also used to separate a soluble solid from a liquid (E.g. seawater) to give a pure sample to each https://www.youtube.com/watch?v=N0f73tbGCRE

Question 37

Chromatography

Answer 37

Used to separate a mixture of dissolved substances in a solution E.g the different colours in a black marker

Question 38

Chromatogram

Answer 38

Chromatography paper with separate ink

Question 39

Reactant

Answer 39

Chemical that reacts together in a chemical reaction

Question 40

Products

Answer 40

The substances formed after a chemical reaction

Question 41

Miscible

Answer 41

Liquids that mix together E.g. alcohol and water

Question 42

Liebig condenser

Answer 42

Piece of equipment used in distillation in which cool water flows condense steam to water

Question 43

Distillate

Answer 43

Clean water at the end of distillation
