A student lists some possible ways to investigate the transfer of kinetic energy using ice in a sample of water. Which procedure would be best to investigate the transfer of kinetic energy
1. Measure the initial temperature of the water using a thermometer.
2. Place a piece of ice in the water and record the time.
3. Stir the water continuously and observe the melting of the ice.
4. Measure the temperature of the water at regular intervals using a thermometer.
5. Record the time taken for the ice to completely melt and the water to reach a certain temperature.
6. Repeat the experiment with different sizes of ice and record the results.
7. Calculate the change in temperature over time for each experiment.
8. Analyze the results and determine the relationship between the amount of ice, time taken to melt, and change in temperature.
The best procedure to investigate the transfer of kinetic energy would be to perform step 4, which involves measuring the temperature of the water at regular intervals using a thermometer. This will help determine the change in temperature over time and provide insights on the transfer of kinetic energy from the ice to the water. Additionally, step 8 will allow for a more thorough analysis of the results and the establishment of any relationships between variables.
