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

Properties of solids

Answer 3

Definite shape
Definite volume
Cannot be compressed
Cannot flow

Question 4

Properties of liquids

Answer 4

No definite shapes
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

Heat energy

Answer 6

In order for a substance to change state ( from a soild to a liquid, or liquid to a gas ) it needs heat energy

Question 7

Latent energy

Answer 7

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

Question 8

The melting point, the boiling point and condensation

Answer 8

The melting point is when both the solid and liquid state exist together (changing from a solid to a liquid).
The boiling point of a liquid is when evaporation begins to happen throughout the liquid (changing from a liquid to a gas).
Condensation is the changing of a gas to a liquid.

Question 9

Diffusion

Answer 9

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 rest of the room

Question 10

Sublimation

Answer 10

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

Question 11

Fourth state of matter

Answer 11

Plasma 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 the ability to conduct electricity.
