Answer 1

To investigate the transfer of kinetic energy using ice in a sample of water, the best procedure would be:

3

This procedure involves measuring the mass of the water and the mass of the ice as it melts, which allows for an assessment of how the presence of ice impacts the temperature (and therefore the kinetic energy) of the water. By measuring these variables, the student can gather data on how the kinetic energy of the water changes as ice melts.

While other procedures also provide useful information, procedure 3 gives the most direct insight into how the melting ice (and subsequent change in water mass) affects the kinetic energy transfer in the system.
