When needed, calculations must be shown for full credit.

1. What is the first law of thermodynamics?

2. Define heat capacity.

3. How much energy is transferred to the surroundings from a 100.0 g sample of copper when the metal’s temperature drops from 100.0°C to 22.0°C?

4. A 466 gram sample of water is heated from 8.50°C to 74.60°C. Calculate the amount of heat absorbed (in kilojoules) by the water.

5. A 100.0 g sample of hot copper is added to a 466.0 g sample of water at 10.0 °C. The final temperature of the water is 12.5°C. How  much energy did the copper lose? What was the initial temperature of the copper?

6. Outline a method you will try for determining the heat capacity of an unknown metal.
