Question

in which example do the particles in water have the most kinetic energy

Answer 1

The kinetic energy of particles in water is influenced by temperature. As the temperature increases, the kinetic energy of the water molecules also increases. Therefore, in a scenario where water is heated, such as boiling water, the particles would have the most kinetic energy compared to water at lower temperatures (like ice or cold water).

For example:
- **Boiling water (100°C or 212°F)**: At this temperature, the water particles have high kinetic energy due to increased thermal motion.
- **Room temperature water (around 20-25°C)**: The kinetic energy is lower than in boiling water but higher than that in cold water.
- **Ice or cold water (0°C or lower)**: The particles have the least kinetic energy in this state.

So, to summarize, particles in **boiling water** exhibit the highest kinetic energy.
