Question

The boiling point of water is:
1. 100°C
2. 50°C
3. 0°C
4. 10°C

Answer 1

Correct Answer - Option 1 : 100°C

The correct answer is 100°C.

• The boiling point of water is 100°C.
• At sea level, vapour pressure is equal to the atmospheric pressure at 100 ˚C, and so this is the temperature at which water boils.
•  Due to this, the temperature required to reach the necessary vapour becomes lower and lower as we get higher above sea level, and the liquid will therefore boil at a lower temperature.

• Water is an inorganic, transparent, tasteless, odorless, and nearly colorless chemical substance, which is the main constituent of Earth's hydrosphere and the fluids of all known living organisms.
• It is vital for all known forms of life, even though it provides no calories or organic nutrients.
• For water, the vapour pressure reaches the standard atmospheric pressure of 1 atmosphere at 100°C.
• So the normal boiling point of water is 100°C (212°F or 373K). The boiling point of pure water increases on the addition of soluble substances such as sugar or common salt.
