The steps are set out in a logical manner that could be followed by another person to calculate the specific heat capacity. 5 - 6 Level 2: The substantive content of a plan is present but may be missing some steps. The plan may not be in a completely logical sequence but leads towards the calculation of the specific heat capacity. 3 - 4 Level 1: Simple statements relating to relevant apparatus or steps are made but they may not be in a logical order. The plan would not allow another person to calculate specific heat capacity. 1 - 2 No relevant content 0 Indicative content • measure the mass of metal • correct use of balance • description of how energy transferred to metal eg electrical work • how energy transfer is measured eg electrical using joulemeter, using ammeter, voltmeter and timer, multiply power of heater by time • how temperature change is found eg measure start and end temperature, using thermometer, calculate temperature change • equate energy transferred = increase in thermal energy store of the metal • calculate specific heat capacity - - [Show More]
