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

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

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

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

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

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?
