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 Power. Point
Starter: Which factors would affect the temperature rise of a metal block when it is heated?
Identify variables for the investigation • Independent • Material (Specific Heat Capacity) • Dependent • Temperature Change (θ) • Control • Mass (1 kg) and Energy supplied (J)
Equation for Specific Heat Capacity E = m × c × θ • 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
Table for different substances and their specific heat capacities Substances Specific heat capacity (J/kg°C) Copper 390 Aluminium 900 Iron 450 Concrete 3400
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?
