1 Learning Outcomes: Rearranging equation for Specific Heat Capacity Topic Equation for Specific Heat Capacity Target Audience: G & T Teacher instructions added in the notes section of PowerPoint

2

3 Investigation – heating aluminium and copper Thermometer Copper Heater Thermometer Aluminium Heater

4 Identify variables for the investigation Independent Dependent Control Material (Specific Heat Capacity) Temperature Change (θ) Mass (1kg) and Energy supplied (J)

5 Equation for Specific Heat Capacity E is the energy transferred in joules, J m is the mass of the substances in kg c is the specific heat capacity in J / kg °C θ (‘theta’) is the temperature change in degrees Celsius, °C E = m × c × θ

6 Table for different substances and their specific heat capacities Substances Specific heat capacity (J/kg°C) Copper390 Aluminium900 Iron450 Concrete3400

7 What did we find out from our investigation? Factors Energy (E) Mass of block (m) Specific heat capacity (c) Temperature (θ) ? How can we use the formula E = m x c x θ to calculate the temperature of the aluminium and copper blocks from our results?
