How are particle models used?

Also know, how is particle theory used in real life?

Some examples:

1. Squeezing syringes containing gas (coloured gas if possible) can show increasing intensity of colour and the idea of particles being pushed closer together.
2. Mixing methylated spirits and water can help to show there must be space between particles (50ml + 50 ml = around 97 ml).

Also, why do we use particle diagrams? Elements and compounds can be represented using particle diagrams, which is a box in which colored balls are draw to represent atoms or molecules. These diagrams can represent elements and compounds, as well as their molecular composition by the types of balls and how they are connected.

Moreover, what is the particle theory used for?

Particle theory helps to explain properties and behaviour of materials by providing a model which enables us to visualise what is happening on a very small scale inside those materials.

What are the main ideas in the particle model?

The particle model has four main tenets: All substances are made of particles.The particles are attracted to each other (some strongly, others weakly). The particles move around (have kinetic energy).
