Powerpoint Description:

This slideshow covers all of the content of the P6 Matter topic from the 2016 OCR 21st Century course, including: density and how to calculate it, the work of James Joule, specific heat capacity and how to practically investigate it, questions on specific heat capacity, specific latent heat and how to calculate it, what happens when ice is heated, energy stores, particle theory, using particle theory to explain density and changes in state, conservation of mass during a change in state, gas pressure and how it is affected by an increase in temperature, the effect of forces, how two forces are needed for twisting or stretching, stretching a spring, how molecules are pulled apart during stretching, force-extension graphs for a spring and a rubber band, elastic limit, plastic deformation, calculating the work done in stretching a spring by considering the area under a graph, elastic potential energy, the relationship between pressure and volume in a gas, atmospheric pressure and what causes it, pressure against depth in a liquid, why objects float or sink, the solar system, what causes orbits, circular motion, radius of a circular path and how it affects speed, how the solar system was formed, work and temperature in a gas, how stars were formed, main sequence stars and the balance of forces, the Big Bang Theory and how red shift gives evidence for it.
