OCR B Matter - Models and Explanations

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

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

Heating and Cooling - The latent heat of a substance and the curves we can plot

The Particle Model [FREE] - This explains a lot

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

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

Gases - How pressure and volume are related

Springs - Stretching, bending and compressing elastic and inelastic objects

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

Upthrust - The force on a submerged object explained

The Earth's Atmosphere - The thin layer of air that surrounds the Earth

Our Solar System - Our home in the universe and the bodies that exist within it

Stars - Their life cycle, from birth to death and beyond

Orbits and Gravity - The ultimate force that allows planets and other objects to remain in orbit

The Universe - This is about literally everything there is
