Matter And Mictures

Question 1

Matter

Answer 1

Anything that occupies space and has mass

Question 2

Mass

Answer 2

Is the amount or matter in an object

Question 3

Three stated of matter

Answer 3

Solids, liquids and gases

Question 4

Properties of solids

Answer 4

1.solids have a define shape
2.solids have a definite volume
3.solids cannot be compressed
4.solids cannot flow

Question 5

Liquids

Answer 5

1.liquids have no define shape
2.liquids have no definite volume
3.liquids cannot be compressed
4.liquids can flow

Question 6

Gases

Answer 6

1. Gases have no defined shape
2. Gases have no definite volume
3. Gases can be compressed
4. Gases can flow

Question 7

Heat energy

Answer 7

In order for a substance to change shape (from a solid to a liquid, or a liquid to a glass) it needs heat energy.

Question 8

Latent heat

Answer 8

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

Question 9

The melting point

Answer 9

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

Question 10

The boiling point

Answer 10

The boiling point of a liquid is when evaporation begins to happen throughout the liquid (changing from a liquid to a gas).

Question 11

Condensation

Answer 11

Is the changing from a gas to a liquid

Question 12

Diffusion

Answer 12

Diffusion 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 other area of the room.

Question 13

Plasma

Answer 13

Is the fourth state of matter. It’s like gas and but can conduct electricity.

Question 14

Mixture

Answer 14

A mixture consists of two or more substances mingles together but not chemically combined e.g. sand and water.

Question 15

What are the four methods of separating mixtures

Answer 15

Filtration,evaporation,distillation,chromatography

Question 16

Filtration

Answer 16

Used to separate small insoluble solids (do not dissolve into liquid) from a liquid by using a filter paper and a funnel to trap the solids.

Question 17

Evaporation

Answer 17

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

Question 18

Insoluble

Answer 18

Does not dissolve in a liquid

Question 19

Soluble

Answer 19

Dissolves in a liquid

Question 20

Residue

Answer 20

The soil left in the filter paper after filtration

Question 21

Distillation

Answer 21

Method of separation used to separate a soluble liquid and its solvent, or two miscible liquids with two different boiling points

Question 22

Miscible

Answer 22

Liquids that mix together e.g. alcohol and water

Question 23

Liebig condenser

Answer 23

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