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
