Q

Weak forces

A

Weak forces between particles mean little energy is needed to overcome them.
Substances with weak forces between particles have low melting and boiling points.

Q

Forces between particles

A

The amount of energy required for substances to change state depends on the strength of the forces between their particles.

Q

Liquids:

A

Particles in liquids are very close together but they move and flow randomly past one another. Liquids have a fixed volume but can change shape and fill a container.

Q

Gasses

A

Particles in gases are far apart and move randomly in all directions. Gases change shape and volume to fill any container.

17
Q

Liquids

A

Particles in liquids are very close together but they move and flow randomly past one another.
Particles in liquids have a fixed volume but can change shape to fill a container.

18
Q

The amount of energy required for substances to change state depends on

A

whether the forces between their particles are strong or weak.

19
Q

Solid to a gas:

A

Sublimation

20
Q

Give
the state of matter in which particles are arranged in layers and are close together?

A

Solid

21
Q

Give
the names of the two transitions of state that occur when a substance loses energy.

A

Condensation
Freezing

22
Q

Potable water

A

Water that is safe to be drank

23
Q

How do we make ground water potable?

A

Sedimentation, chlorination, filtration

24
Q

What is the name of the change of state from gas to solid?

A

Depositing

25
Q

What is the name of the change of state from gas to liquid?

A

Condensing

26
Q

In what state change do the particles gain energy, vibrate more and become able to move freely in all directions

A

Boiling

27
Q

In what state change do the particles have less energy, move about less and move to an organised structure

A

Freezing

28
Q

How do we make ground water potable?

A

sedimentation, filtration and chlorination

29
Q

How do we make not potable water potable?

A

filtration, chlorination and sedimentation

30
Q

What is a mixture

A

2 or more substances that are not chemically joined

31
Q

What is a compound

A

Composed of 2 separate elements chemically joined

32
Q

Heating curve first curve is:

A

Melting point

33
Q

Heating curve 2nd point:

A

Boiling point

34
Q

Why is it important to use distilled water in a laboratory?

A

because it does not contain impurities like dissolved ions. Tap water contains such impurities, which can interfere with our chemical test via side reactions.

35
Q

Sedimentation:

A

It is a process that removes solids that float and settle in the water.

36
Q

Filtration

A

Water filtration removes germs by physically blocking them while letting the water pass through the filter

37
Q

Chlorination

A

is the process of adding chlorine to drinking water to kill parasites, bacteria, and viruses.
