Procedure 4: Determine temperature and mass of water. Put ice in water. Record the time for ice to melt.
To investigate the connection between kinetic energy and temperature, the most appropriate experimental setup would be to place one drop of food coloring in a cup with 50 mL of water at 10ºC and to place one drop of food coloring in a second cup with 50 mL of water at 40ºC. This setup allows the student to compare the movement (or spread) of the food coloring in the two cups, which is an indicator of kinetic energy.
To conduct this experiment, the student should follow these steps:
1. Fill two separate cups with 50 mL of water each. Label one cup as "10ºC" and the other as "40ºC."
2. Use a thermometer to measure the temperature of the water in each cup. Adjust the temperature of the water using a hot plate or by adding ice cubes until the desired temperatures are reached.
3. Once the temperatures are stable, place one drop of food coloring in the "10ºC" cup and observe how it spreads.
4. Repeat the same process by placing another drop of food coloring in the "40ºC" cup and observe its spread.
5. Make observations and record data about the movement of the food coloring in each cup. Note any differences in the spreading patterns and the time it takes for the food coloring to mix with the water.
6. Analyze the data and draw conclusions regarding the connection between kinetic energy and temperature.
