Question

Find the odd-one :

Accepted Answer

Option 1, Oxygen, is the correct answer as the odd-one-out for the following reasons:

1. **Explanation for Option 1 (Oxygen):**
   - Oxygen is a chemical element with the symbol O and atomic number 8. It is a gas at room temperature and is a fundamental component of the Earth's atmosphere. Oxygen is essential for respiration in living organisms and is not a form of water.
   - In contrast, the other options (Ice, Water, Steam) are different states of the same substance, H2O, which is water. Therefore, Oxygen stands out as it is not a state of water but a separate element altogether.

2. **Explanation for Option 2 (Ice):**
   - Ice is the solid state of water. It forms when water freezes at 0°C (32°F). Ice is simply water in a solid form, and it shares the same chemical composition as water and steam (H2O).

3. **Explanation for Option 3 (Water):**
   - Water is the liquid state of H2O. It is the most common form of this compound on Earth and is essential for all known forms of life. Water is the baseline state from which ice and steam are derived through changes in temperature.

4. **Explanation for Option 4 (Steam):**
   - Steam is the gaseous state of water. It is produced when water boils at 100°C (212°F) under standard atmospheric pressure. Like ice and liquid water, steam is composed of H2O molecules.

In summary, Options 2, 3, and 4 (Ice, Water, Steam) are all different physical states of the same substance, water (H2O). Option 1, Oxygen, is distinct because it is a separate chemical element and not a state of water. This makes Oxygen the odd-one-out in this list.
