Answer 8

A liquid

Question 9

Which state(s) of matter have a fixed shape?

Answer 9

A solid

Question 10

Which state of matter can be compressed and why?

Answer 10

A gas because there are large spaces between the particles

Question 11

What do we call the movement of particles in a liquid or gas from a high to low concentration?

Answer 11

Diffusion

Question 12

When a solid dissolves in a liquid, we form a what?

Answer 12

Solution

Question 13

Where does the solid go when it dissolves in a liquid?

Answer 13

In between the liquid particles

Question 14

What do we call the solid that dissolves in the liquid?

Answer 14

The solute

Question 15

What do we call the liquid that the solid is dissolved in?

Answer 15

The solvent

Question 16

If solid dissolves in a liquid we say it is what?

Answer 16

Soluble

Question 17

When two or more different substances are found together we call it a what?

Answer 17

Mixture

Question 18

What method would you use to separate sugar that was dissolved in water and why does it work?

Answer 18

Evaporation - the water boils and turns to a gas at a lower temperature than the sugar

Question 19

What method would you use to separate the ink in different coloured felt pens and why does it work?

Answer 19

Chromatography - the colours that travel further up the filter paper are more soluble

Question 20

What method would you use to separate sand from gravel and why does it work?

Answer 20

Filtering - because the sand is a different size to the gravel

Question 21

What method would you use to separate iron filings from sand and why does it work?

Answer 21

Magnetism - because iron is magnetic

Question 22

What method would you use to separate two liquids such as meths and water, regather one of the liquids and why does it work

Answer 22

Distillation - because one liquid boils at a lower temperature than the other

Question 23

Describe five properties of metals that makes them different from most non-metals

Answer 23

Malleable
Ductile
Good conductors of heat and electricity
Strong
Shiny lustre

Question 24

Why are metals used for cooking pots?

Answer 24

Good conductors of heat

Shiny lustre so attractive

Question 25

Why is copper used for electrical wires?

Answer 25

Good conductor of electricity

Ductile

Question 26

What does malleable mean?

Answer 26

Able to be shaped

Question 27

What does ductile mean?

Answer 27

Able to be bent into a wire

Question 28

Is plastic a metal or non-metal?

Answer 28

Non-metal

Question 29

Why is plastic used as a handle of an electric jug?

Answer 29

It is an insulator so it doesn’t conduct heat so you won’t burn yourself
