Responses

water at 40°C in a swimming pool
water at 40°C in a swimming pool

an iceberg at 0°C
an iceberg at 0°C

water at 37°C in a glass
water at 37°C in a glass

a drop of water at 90°C
a drop of water at 90°C

Answer 1

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

Kinetic energy of particles is directly related to temperature; therefore, the higher the temperature, the greater the average kinetic energy of the particles. In this case, the water at 90°C has the highest temperature among the options given.
