gravitational potential energy, Ep, in joules, J mass, m, in kilograms, kg gravitational field strength, g, in newtons per kilogram, N/kg height, h, in metres, m 6.1.1.3 The distribution of energy in a system can change. This change can be calculated. The equation is covered in detail in section 6.3.2 The specific heat capacity of a substance is the amount of energy required to change the temperature of one kilogram of the substance by one degree Celsius. Calculate changes in the way energy is stored when a system is changed by heating. Use calculations to show how the overall energy in a system is redistributed when the system is changed. The amount of energy stored in or released from a system as its temperature changes can be calculated using the equation: 2 Ask students to explore questions such as: What determines how fast the temperature of a substance increases? Presenting and writing descriptions and explanations: Describe how the energy stored in a system changes when it is heated. Calculate: Calculate the increase in stored energy when a substance is heated. Why are concrete blocks used as thermal storage heaters? Why does the temperature of a pan of oil increase faster than a pan of water? Why does the filling of a pie feel hotter than the pastry even though it has been in the same oven? Obtaining and presenting primary evidence. Required practical: Investigation to determine the specific heat capacity of one or more materials. (10.2.14) The investigation will involve linking the decrease of one energy store (or work done) to GCSE Boardworks – Energy Efficiency, Energy and Movement (Mini White Boards for teacher’s Q&A or activities) Kinetic energy: Video clip
