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

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

Question 4

Properties of liquids

Answer 4

1. Liquids have no definite shape
   2.liquids have a definite volume
2. Liquids cannot be compressed
   4.liquids can flow

Question 5

Gases

Answer 5

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

Question 6

Energy

Answer 6

In order for a substance to change state (from a solid to a liquid ,or a liquid to a gas) it needs heat energy
As a substance changes state ,it uses latent heat there is no change to temperatures,but the state of the material changes

Question 7

Condensation

Answer 7

The melting point is when both the solid and liquid state exist together( changing from a solid to a liquid )

The boiling point 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

Sublimation 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 8

Diffusion

Answer 8

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 9

Fourth state of matter

Answer 9

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.
