Name gaseous form of water.

Answer

**Step-by-Step Solution:**

1. **Understanding the States of Water**: Water exists in three states - solid (ice), liquid (water), and gas (water vapor).

2. **Identifying the Gaseous Form**: The question specifically asks for the gaseous form of water.

3. **Defining Water Vapor**: The gaseous form of water is known as "water vapor." This occurs when water is heated to a high temperature, causing it to change from liquid to gas.

4. **Conditions for Water Vapor Formation**: Water vapor is produced when water reaches its boiling point, which is typically at 100 degrees Celsius at standard atmospheric pressure. However, water can also evaporate at lower temperatures.

5. **Conclusion**: Therefore, the gaseous form of water is called water vapor.

**Final Answer**: Water vapor
