Question

Which object will have particles with the highest average kinetic energy A water at 40 Celsius in a swimming pool B water at 37 C in a glass C an iceberg at 0 Celsius D a drop of water at 90 Celsius

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.

Given the options:

A. Water at 40 °C in a swimming pool
B. Water at 37 °C in a glass
C. An iceberg at 0 °C
D. A drop of water at 90 °C

The temperatures are as follows:

- A: 40 °C
- B: 37 °C
- C: 0 °C
- D: 90 °C

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

So, the object with the highest average kinetic energy is **D: a drop of water at 90 °C**.
