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

The object that will have particles with the highest average kinetic energy is the drop of water at 90°C. The average kinetic energy of particles increases with temperature, so the higher the temperature, the higher the average kinetic energy.

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

Given the choices provided:

1. Water at 40°C in a swimming pool: The average kinetic energy of particles in water at 40°C will be higher than the particles in an iceberg at 0°C, but it will not be as high as the other options.

2. A drop of water at 90°C: The average kinetic energy of particles in water at 90°C will be higher than water at 40°C or water at 36°C.

3. Water at 36°C in a glass: The average kinetic energy of particles in water at 36°C will be lower than water at 40°C or 90°C.

4. An iceberg at 0°C: The average kinetic energy of particles in an iceberg at 0°C will be the lowest among the given options.

Therefore, the correct answer is: A drop of water at 90°C (option 2) will have particles with the highest average kinetic energy.

To determine which object will have particles with the highest average kinetic energy, we need to consider the relationship between temperature and kinetic energy. According to the kinetic theory of gases, the average kinetic energy of particles is directly related to their temperature.

Kinetic energy is the energy of motion possessed by particles, and temperature is a measure of the average kinetic energy of particles in a substance.

In this case, we can compare the temperatures given for each object and determine which one has the highest temperature. The object with the highest temperature will have particles with the highest average kinetic energy.

Let's compare the temperatures given for each object:

1. Water at 40°C in a swimming pool.
2. A drop of water at 90°C.
3. Water at 36°C in a glass.
4. An iceberg at 0°C.

From these options, the drop of water at 90°C has the highest temperature. Therefore, the drop of water at 90°C will have particles with the highest average kinetic energy among the given objects.

To summarize, the object with the highest temperature will have particles with the highest average kinetic energy. In this case, the drop of water at 90°C has the highest temperature, hence the particles in it will have the highest average kinetic energy.
