  1. If the specific heat capacity of water is 4180 J/(kg · ° C) how much thermal energy is needed to raise the temperature of 2.2 kg of water from 20 ° C to the boiling point? (Assume two significant digits.)
  2. A copper pot is sitting on a burner. The pot has a mass of 1.20 kg and is at a temperature of 130.0 °C . If the pot cools to a room temperature of 21.0 ° C, how much thermal energy does it release to the surroundings? The specific heat capacity of copper is 380 J/(kg · ° C). (Assume three significant digits.)
  3. A 60 g sample of metal is heated to 100 ° C and is then placed in 200 g of water with an initial temperature of 10 ° C. The metal­water combination reaches a final temperature of 15.6 ° C. Determine the specific heat capacity of the metal and it's identity.
  4. A 200 g piece of iron at 350 ° C is submerged in 300 g of water at 10 ° C to be cooled quickly. Determine the final temperature of the iron­water combination. (Assume two significant digits.)
