Which object will have particles with the highest average kinetic energy?

Question

(1 point)
• a drop of water at 90°C
• water at 40°C in a swimming pool
• an iceberg at 0°C
• water at 37°C in a glass

Answer 1

The object with particles having 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 its temperature. Higher temperatures correspond to higher average kinetic energy of the particles. Therefore, among the options provided, the drop of water at 90°C has the highest average kinetic energy.
