Activity

Part A

Read the experiment. Type in hypotheses about what will happen after heating the water, and then after letting it cool. Then do the experiment and note your observations.

Procedure

1. Pour two glasses of water in a pan.
2. Heat it on a stove or Bunsen burner.
3. Turn off the heat after two minutes.
4. Take a kitchen thermometer and carefully record the temperature of the water and the pan itself.
5. Let the pan cool down.
6. Record the temperature of the water and the pan after 15 minutes.

Hypothesis: Which do you think will be warmer after 2 minutes of heating, the pan or the water inside the pan? Which do you think will be warmer after 15 minutes of cooling - the pan or the water inside the pan?
