Answer:

In the previous chapter we learnt that scientists use models when they want to describe things that are difficult to understand. We discussed a model of the atom that helped us to imagine what atoms look like.

This model of the atom shows us where the different sub-atomic particles can be found. The sub-atomic particles shown here are the proton, neutron and electron.

Theories are similar to models. They explain scientific phenomena (things and events that can be described and explained in scientific terms) using pictures and words.

What does the particle model of matter teach us?

The particle model describes matter in a very specific way. It describes four important aspects of matter:

All matter is made up of particles that are incredibly small - much too small to see with the naked eye. The particles can be atoms or combinations of atoms that are bonded.

There are forces between the particles.

The particles in matter are always moving. The more energy they have, the faster they move.

The spaces between the particles in matter are empty. You might assume that the spaces between particles are filled with air, but this is not the case. They contain nothing at all.

If you need to, turn back to chapter 1 to revise the terms atom, element, compound and molecule and how they relate.

Why is the particle model of matter so useful?

The particle model of matter is one of the most useful scientific models because it describes matter in all three states. Understanding how the particles of matter behave is vital if we hope to understand science!

The model also helps us to understand what happens to the particles when matter changes from one state to another.

The following diagram shows different changes of state, as well as which processes are the reverse of each other. Melting and freezing are the reverse processes of each other and so are evaporation (boiling) and condensation.

Under special circumstances, a solid can change directly into a gas without melting first. This process is known assublimation and its reverse (when a gas changes directly into a solid without condensing first) is called deposition.

Answer:

The activity is to explain the different properties of matter.

Explanation:

  • Take the following objects; an empty vessel, a balloon a bottle of water, air/ballooon pump and a thick book
  • First, but the thick book in the empty vessel.
  • The book did not change its shape, it has a fixed shape and hence is a solid
  • Next, pour water from the bottle into the empty vessel.
  • The water flows and takes the shape of the container it is in so it is a liquid
  • Finally, using the air pump, pump air inside the balloon
  • As you pump more air, the balloon increases in size, the air also takes the shape of the container it is in, it is a gas

The above activity will help you understand the different properties of solids, liquids and gases
