change in thermal energy, ΔE, in joules, J mass, m, in kilograms, kg specific heat capacity, c, in joules per kilogram per degree Celsius, J/kg°C temperature change, Δθ, in degrees Celsius, °C The specific heat capacity of a substance is the amount of energy required to raise the temperature of one kilogram of the substance by one degree Celsius. Presenting and writing descriptions and explanations: Describe what is happening at an atomic level when a substance is heated. Developing explanations using ideas and models: Give students an opportunity to create own models to explain what is happening when a solid is heated. This can be in the form of a diagram, a 2D or 3D model as they see fit. Calculate: Carry out calculations involving specific heat capacity. Students should also be able to rearrange the equation to find any unknown in the equation. Presenting and writing arguments: Evaluate the use of concrete in storage heaters: Why is concrete used? the increase in temperature and subsequent increase in thermal energy stored. Working critically with primary and secondary evidence: How much energy is stored in a crisp? Do some research to find out the published figures and then investigate. Working scientifically: Research different methods for measuring specific heat capacity. Design safe practical procedures that allow data to be collected. Select suitable apparatus for carrying out the experiment accurately and safely. Identify possible hazards, the risks associated with these hazards, and methods of minimising the risks. Make measurements with appropriate precision and record data in appropriate tables.
