States Of Matter

Question 1

Matter

Answer 1

Anything that occupies space and has mass

Question 2

Mass

Answer 2

Is the amount of matter in an object

Question 3

Solids

Answer 3

Properties of solids:
Definite volume
Definite shape
Cannot be compressed
Cannot flow

Question 4

Liquids

Answer 4

No definite shape
Definite volume
Cannot be compressed
Can flow

Question 5

Gases

Answer 5

No definite shape
No definite volume
Can be compressed
Can flow

Question 6

Energy

Answer 6

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

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

Question 7

Melting point

Answer 7

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

Question 8

Boiling point

Answer 8

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

Question 9

Condensation

Answer 9

Is the changing of a gas to a liquid

Question 10

Sublimation

Answer 10

Some substances do not change from a solid to a liquid when they melt, they change straight from a solid to a gas E.G. solid carbon dioxide is known as dry ice and turns into a gas when heated

Question 11

Diffusion

Answer 11

Diffusion is the movement of particles from an area of high concentration e.g. spray perfume in one corner of the room, and it spreads to the rest of the room

Question 12

Plasma

Answer 12

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

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 ability to conduct electricity.
