Understanding Kinetic Energy in States of Matter
Kinetic energy is the energy of motion, and in the context of particles in different states of matter, it varies significantly depending on temperature and state.
States of Matter and Temperature
- **Steam at 100°C:**
- Particles are in a gaseous state, moving rapidly and freely.
- High kinetic energy due to increased temperature.
- **Water at 0°C:**
- Particles are in a liquid state, moving but less freely than in gas.
- Moderate kinetic energy.
- **Water at 100°C:**
- Particles are in a liquid state, but transitioning to gas.
- Higher kinetic energy, similar to steam.
- **Ice below 0°C:**
- Particles are in a solid state, vibrating in fixed positions.
- Minimal kinetic energy as the temperature is low.
Why Ice Below 0°C Has Minimum Kinetic Energy
- **Solid State Characteristics:**
- In solids like ice, particles are closely packed and primarily vibrate in place rather than moving freely.
- **Low Temperature Effect:**
- Below 0°C, the temperature decreases the energy of the particles, resulting in lower kinetic energy.
- **Comparison with Other States:**
- The kinetic energy of particles in steam and water (both at higher temperatures) is significantly greater than that of ice, making ice the state with minimum kinetic energy.
Conclusion
In summary, the particles of ice below 0°C have the minimum kinetic energy among the given options due to their solid-state arrangement and lower temperature, which restricts their motion compared to liquids and gases at higher temperatures.

Which of the following has minimum kinetic energy?a)Particles of steam...
Kinetic energy is the energy that an object contains in itself because of its motion. The reason is that steam is in the form of gases in which the particles of gases are much apart from one another. The space between the particles of gases is very large. When we heated the particles of gases, it can move very rapidly. Hence, its kinetic energy is maximum.
