1. The document shows the calculation of specific heat (c) from the heat equation and derives that the units of specific heat are cal/g°C. 2. It asks which block, lead or copper, will require more heat to increase temperature by 70°C if they have the same initial temperature and mass. Lead has a lower specific heat than copper, so the lead block will require less heat. 3. It provides a problem to calculate the specific heat of a new alloy, given the mass of the alloy and aluminum calorimeter cup, initial and final temperatures, and the mass of water.
