Q

What energy does a substance use when changing state

A

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

A

Condensing

21
Q

Solid to liquid

A

Melting

22
Q

Liquid to solid

A

Freezing

23
Q

Diffusion

A

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

24
Q

A

Please

25
Q

Plasma i

A

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

26
Q

Physical change

A

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

27
Q

Chemical change

A

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

28
Q

During a chemical reaction

A

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

29
Q

Law of conservation of mass

A

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

30
Q

A mixture

A

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

31
Q

There are four method of separating mixture

A

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

32
Q

Filtration

A

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

33
Q

Evaporation

A

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

34
Q

Law of conservation of mass

A

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

35
Q

A mixture

A

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

36
Q

Distillation

A

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

37
Q

Chromatography

A

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

38
Q

Chromatogram

A

Chromatography paper with separate ink

39
Q

Reactant

A

Chemical that reacts together in a chemical reaction

40
Q

Products

A

The substances formed after a chemical reaction

41
Q

Miscible

A

Liquids that mix together E.g. alcohol and water

42
Q

Liebig condenser

A

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

43
Q

Distillate

A

Clean water at the end of distillation
