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?
To investigate the transfer of kinetic energy using ice in a sample of water, the best procedure would be to:
1. Set up an insulated container with a known amount of water.
2. Measure the initial temperature of the water.
3. Add a measured quantity of ice cubes to the water.
4. Stir the water and ice mixture gently for a specific time.
5. Record the final temperature of the water.
6. Calculate the change in temperature (∆T) by subtracting the initial temperature from the final temperature.
7. Calculate the transferred thermal energy (∆Q) using the formula ∆Q = mc∆T, where m is the mass of water, c is the specific heat capacity of water, and ∆T is the change in temperature.
8. Repeat the experiment multiple times with different initial water temperatures and/or amounts of ice to gather more data.
9. Analyze the data to observe trends in the transferred kinetic energy with changes in initial temperature and amount of ice.
10. Draw conclusions and make inferences about how the transfer of kinetic energy occurs between water and ice based on the results.
