Answer options

  1. 0°C
  2. 32°C
  3. 212°C
  4. 100°C

Correct answer and explanation

Correct answer: 100°C

Explanation: ✅ Correct Answer: D) 100°C 📚 Explanation: The boiling point of water is defined as 100°C (or 212°F) at sea level. This temperature is used as a standard reference point for the Celsius temperature scale. However, the boiling point decreases at higher altitudes because the atmospheric pressure is lower, requiring less heat for water molecules to escape into the vapor phase.
