In science we use models to represent the world around us. The particle model is essential in understand how 'stuff' behaves and everything in chemistry!

Choose your topic:

Density and Pressure

Density [FREE] - The amount of 'stuff' in a given space

Pressure - In fluids this causes a force at right angles to a surface

Change of State

The Particle Model [FREE] - This explains a lot

States of Matter - Solids, liquids and gases, and changing from one to another

Specific Heat Capacity [FREE] - Linked to the thermal energy stored by an object

Heating and Cooling - The constant temperature during a phase change

Ideal Gas Molecules

Gases - How particles cause pressure and how volume, pressure and temperature are related
