Answer 1

To investigate the transfer of kinetic energy using ice in a sample of water, the best procedure would be Procedure 1:

• Record temperature of water.
• Put ice in water.
• Record temperature after ice melts.

This procedure effectively measures the transfer of kinetic energy, as the temperature change of the water before and after adding ice directly relates to the kinetic energy of the water molecules.

Procedure 3 also involves the mass of the water but does not directly address the kinetic energy transfer as clearly as Procedure 1 does.

Procedures 2 and 4 do not provide sufficient quantitative data for assessing kinetic energy transfer.

Thus, Procedure 1 is the most suitable for your investigation.
