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

Question

water at 40 C in a swimming pool
a drop of water at 90 C
water at 37 Cin a glass
an iceberg at 0 C

Answer 1

The average kinetic energy of particles in a substance is directly related to its temperature. The higher the temperature, the greater the average kinetic energy of the particles.

Let's examine the temperatures of the objects you mentioned:

1. Water at 40 °C in a swimming pool: 40 °C
2. A drop of water at 90 °C: 90 °C
3. Water at 37 °C in a glass: 37 °C
4. An iceberg at 0 °C: 0 °C

Among these options, the drop of water at 90 °C has the highest temperature, and therefore, it will have the highest average kinetic energy of its particles.

So, the answer is a drop of water at 90 °C.
