Q

Latent heat

A

As a substance changes state it uses latent heat. There is no change to temperature , but the state of the material changes

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 spreads to the rest of the room

Q

Plasma

A

It is very similar to a gas, in fact plasma is a gas
That can carry an electric charge. Plasma
Particles spread out and move around
Randomly, but unlike gas, plasma has the
Ability to conduct electricity.

Q

Mixture

A

A mixture consists of two or more
Substances mingled together but not
Chemically combined E.g. sand and water.

There are 4 methods of separating mixtures
Filtration
Evaporation
Distillation
Chromatography

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

Q

Evaporation

A

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

17
Q

Physical change

A

Physical change: no change in particles, just
the particle arrangement and energy, easy lo
reverse eg mixing water and salt

18
Q

Chemical change

A

A chemical reaction takes place and a new substance is formed, very difficult to reverse E.g. burning a match

19
Q

During a chemical reaction

A

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

20
Q

Law of conversation of mass

A

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

21
Q

Distillation

A

Used to separate two liquids with
different boiling points such as
alcohol (boils a 78°) and water
(boils at 100 9). Also used to
separate a soluble solid from a
liquid (e.g. seawater) to give a pure sample of each

22
Q

Chromatography

A

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

23
Q

Mixture

A

Mixture – consists of two or more
substances mingled together but not
Chemically combined

24
Q

Filtration

A

Filtration – used to separate an
insoluble solid and a liquid

25
Q

Insoluble

A

Insoluble – does not dissolve in a liquid

26
Q

Soluble

A

Soluble – dissolves in a liquid

27
Q

Residue

A

Residue - the soil left in the filter paper after
filtration

28
Q

Filtrate

A

Filtrate - the clean water that comes after
filtration

29
Q

Solvent

A

Solvent - the liquid that a solid is dissolved
into

30
Q

Solute

A

Solute - the solid that is left behind after
evaporation

31
Q

Miscible

A

Miscible - Liquids that mix together e.g.
alcohol and

32
Q

Liebig condenser

A

Liebig condenser - piece of equipment used in
distillation in which cool water flows to
condense steam to water

33
Q

Distilate

A

Distillate - clean water at the end of distillation

34
Q

Chromatogramme

A

 Chromatogram - chromatography paper with
separated ink

35
Q

Reactant

A

Reactant: chemicals that react together in a
chemical reaction

36
Q

Products

A

Products: the substances formed after a
chemical reaction
