To investigate the transfer of kinetic energy using ice in water, the best procedure would be:
Procedure 1
This is because it involves recording the temperature changes before and after the ice melts, which directly relates to the kinetic energy transfer between the ice and the water. Temperature is a measure of the average kinetic energy of the molecules, so observing the changes in temperature provides valuable information about how the kinetic energy is transferred during the melting process.
Therefore, the correct response is 1.
