Matter

1. Define matter (explain what matter is) ☐

Matter is anything that has both mass and volume.

Matter is all that which makes up the world,

please list examples (10) of such .....

1. Name three states of matter ☐

There are 4 states of matter that are common to us in life, Solids, Liquids, Gases and Plasmas

In Plasmas the particles have more energy than in a gas.
In Gases the particles have more energy than in a liquid

In Liquids the particles have more energy than in a solid.

1. Describe and explain ‘particle theory’ ☐

All matter is composed of tiny indivisible particles too small to see. Some of these particles are called Atoms, other collections are called molecules, sometimes they are referred to as ions.

1. ☐

2. Describe the properties of a liquid ☐

3. Describe the properties of a gas ☐

4. Explain diffusion and give some examples ☐

5. Explain the term ‘changing of state’ ☐

6. Define melting and describe the movement of particles as it occurs ☐

7. Define boiling and describe the movement of particles as it occurs ☐

8. Define freezing and describe the movement of particles as it occurs ☐

9. Define condensing and describe the movement of the particles as it

occurs

14. Define evaporation and describe the movement of particles as it occurs. ☐

Mass Changes for a Physical reaction

Freezing Water

Mass of Beaker = g

Mass of Beaker + Water = g

Mass of Water = g

freeze it

Mass of Beaker + Ice = g

Chemical reactions

When you burn paper, what happens?

Does the paper disappear ?

What happens that which makes up the paper?

Particles, every thing is made of Particles

Particles can be

Atoms

or Molecules

All the Atoms can be found on the periodic table

Molecules are when 2 (or more) atoms are joined together by forces, to make a bigger particle.

H₂O water molecule made of Hydrogen & Oxygen

CO₂

CO

NaCl Salt Molecule

H₂SO₄

An element is a pure substance that has only one type of atom in it.

All elements have a 1 word Name and a Symbol and can be found on the periodic table

all known elements are listed in the Periodic Table;

In the passed 120 years we have found out that atoms are not just particles but made of other particles

Atoms are made of Protons Neutrons and electrons
