Options

A. `S_("vapour") gt S_("solid") gt S_("liquid")`
B. `S_("vapour") gt S_("liquid") gt S_("solid")`
C. `S_("vapour") lt S_("liquid") lt S_("solid")`
D. `S_("vapour") = S_("liquid") gt S_("solid")`

Explanation

To solve the question regarding the correct statements about entropy (S), we will analyze the properties of entropy in relation to the states of matter: solid, liquid, and vapor (gas).

### Step-by-Step Solution:

1. **Understanding Entropy**:
- Entropy (S) is a thermodynamic quantity that measures the degree of disorder or randomness in a system. The higher the entropy, the greater the disorder.

2. **States of Matter**:
- The three common states of matter we will consider are solid, liquid, and vapor (gas).
- In solids, particles are closely packed and have limited movement, resulting in low entropy.
- In liquids, particles are more spaced out compared to solids and can move more freely, leading to higher entropy than solids but lower than gases.
- In vapors (gases), particles are far apart and move freely, resulting in the highest entropy.

3. **Ranking Entropy**:
- Based on the understanding of the states of matter, we can rank the entropy from lowest to highest:
- Solid (lowest entropy)
- Liquid (medium entropy)
- Vapor (highest entropy)

4. **Conclusion**:
- The correct order of entropy is: Vapor > Liquid > Solid.
- Therefore, the correct statement regarding entropy is that vapor has the highest entropy, followed by liquid, and solid has the lowest entropy.

### Final Answer:
- The correct statement about entropy is that the order of entropy is: Vapor > Liquid > Solid.
