1. Fix the ring to the stand with the clamp | 1. Place a beverage can filled with cold water into a beaker filled with warm water. |
2. Place the beaker on the stand support and place the empty can into the beaker. | |
3. Place the thermometer in each empty can and beaker without touching it, then hang the thermometer on the ring. | 2. Hang two alcohol thermometers on a stand and place them in a beverage can and a beaker, respectively. |
4. Add about 2/3 of cold water into the empty can and about 1/2 of warm water into the beaker. | |
5. As soon as the experiment begins, measure the temperature of the water in the can and beaker. | 3. Measure the temperature of the water in the beverage can and beaker every minute. |
6. Measure the temperature of the water in the can and beaker every minute. | |
7. Talk about how the temperatures of two substances of different temperatures change when they come into contact. | 4. Talk about how the temperatures of two substances of different temperatures change when they come into contact. |
