In all the three states of water (i.e.ice,liquid and vapour)chemical composition of water

Options

A. is very different
B. remains same
C. sometime1 and sometime2
D. none of the above

Answer

To solve the question regarding the chemical composition of water in its three states (ice, liquid water, and water vapor), we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Chemical Composition of Water**:
- Water is chemically represented as H₂O, which means it consists of two hydrogen (H) atoms and one oxygen (O) atom.

2. **Consider the Three States of Water**:
- The three states of water are:
- Ice (solid state)
- Liquid water (liquid state)
- Water vapor (gaseous state)

3. **Analyze the Chemical Composition in Each State**:
- In all three states (ice, liquid water, and water vapor), the chemical formula remains H₂O.
- This indicates that the number of hydrogen and oxygen atoms does not change regardless of the state of water.

4. **Evaluate the Options Given**:
- **Option 1**: "Very different" - This is incorrect because the composition does not change.
- **Option 2**: "Remains the same" - This is correct as the composition of water is always H₂O.
- **Option 3**: "Sometimes one and sometimes two" - This is incorrect as the composition is consistently H₂O.
- **Option 4**: "None of these" - This is also incorrect since option 2 is valid.

5. **Conclusion**:
- The correct answer is **Option 2**, which states that the chemical composition of water remains the same in all three states.

### Final Answer:
The chemical composition of water in all three states (ice, liquid, and vapor) remains the same (H₂O).
