The object with the highest average kinetic energy will be a drop of water at 90°C.
Kinetic energy of particles in a substance is directly related to the temperature of that substance. The higher the temperature, the more kinetic energy the particles have. Thus, among the given options, the drop of water at 90°C has the highest average kinetic energy.
The correct response is: The particles gain both potential and kinetic energy.
As water heats up, its temperature rises, which means the kinetic energy of the particles increases. Additionally, when water reaches its boiling point and begins to transition to steam (water vapor), the particles gain potential energy as they overcome the intermolecular forces holding them in the liquid state. Thus, both kinetic and potential energy increase during this process.
