Answer 1

The object that will have particles with the highest average kinetic energy is a drop of water at 90°C.

The average kinetic energy of particles is directly related to temperature; higher temperatures correspond to higher average kinetic energy. Therefore, the drop of water at 90°C will have particles moving faster on average than those in the other examples.
