The water level.. .... When a pinch of salt is dissolved in a glass of water?

Options

A. Increases
B. decreases
C. remains the same
D. None of the above

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks what happens to the water level when a pinch of salt is dissolved in a glass of water.

2. **Analyzing the Situation**: When salt is added to water, it dissolves. This means that the salt molecules will interact with the water molecules.

3. **Molecular Interaction**: Water molecules have spaces between them. When salt is added, the salt molecules fit into these spaces between the water molecules.

4. **Effect on Water Level**: Since the salt molecules occupy the spaces between the water molecules without adding extra volume to the water, the overall volume of the water does not increase.

5. **Conclusion**: Therefore, the water level remains the same after dissolving a pinch of salt in it.

6. **Final Answer**: The water level remains the same.
