Energy • List renewable energy resources • Explain why renewable energy use is increasing • Which fuels contribute to global warming? • Describe advantages and disadvantages of energy resources • What type of energy does a battery store? Why might this energy reduce? • How can we calculate power? • What equations are there for energy? • How is energy transfer reduced in buildings? Particle Physics • What happens to particles in solids liquids and gases when they are heated? • Write the equation for specific latent heat of fusion • How could we determine the density of a regular and irregular shaped object? • What is the equation for specific heat capacity and what is it used for? Electricity • Why might some appliances not need an earth wire? • What is the equation that links charge flow, current and time? • What are the circuit symbols for a fuse & resistor • What is ohms Law? • What do the current potential difference graphs for resistors, bulbs and diodes look like? • What are the rules for series and parallel circuits? Atomic structure • What are the 3 types of radiation and which is the most penetrating, ionising and which has the longest range in air? • How do we work out the protons and neutrons in an atom? • Draw the plum pudding model of an atom • Why is the overall charge on an atom 0? • What is half life of a radioactive isotope? • How is the count rate of an radioactive isotope measured?
