Which state of matter has maximum thermal enegy ?

Options

A. Solid
B. Liquid
C. Gas
D. None of these

Answer

To determine which state of matter has the maximum thermal energy, we can analyze the kinetic energy of the particles in each state: solid, liquid, and gas.

### Step-by-Step Solution:

1. **Understanding Thermal Energy**:
- Thermal energy is the total kinetic energy of the particles in a substance. It depends on both the temperature and the number of particles present.

2. **States of Matter**:
- **Solid**: In solids, particles are closely packed in a fixed arrangement and can only vibrate in place. This limits their kinetic energy.
- **Liquid**: In liquids, particles are close together but can move past each other. This allows for more kinetic energy than in solids.
- **Gas**: In gases, particles are far apart and move freely in all directions. They have the highest kinetic energy due to their random motion.

3. **Comparing Kinetic Energy**:
- The kinetic energy of particles increases with temperature. Gases, having particles that are in constant random motion, possess the highest kinetic energy compared to liquids and solids.

4. **Conclusion**:
- Since gases have particles that move freely and rapidly, they have the maximum thermal energy among the three states of matter.

### Final Answer:
The state of matter that has maximum thermal energy is **gas**.
