1. What is Water Boiling Point?

The boiling point of water is the temperature at which water changes from a liquid to a gas. At standard atmospheric pressure (1013.25 hPa), water boils at 100°C (212°F). This temperature decreases with increasing altitude due to lower atmospheric pressure.

2. How Does the Calculator Work?

The calculator uses the standard formula:

Where:

• \( T_b \) — Boiling point temperature (°C)
• \( Altitude \) — Elevation above sea level (meters)

Explanation: The boiling point decreases by approximately 1°C for every 300 meters increase in altitude due to reduced atmospheric pressure.

3. Importance of Boiling Point Calculation

Details: Knowing the exact boiling point is crucial for cooking, scientific experiments, industrial processes, and safety considerations at different altitudes.

4. Using the Calculator

Tips: Enter your altitude in meters above sea level. For more precise calculations, you can optionally enter the current atmospheric pressure in hectopascals (hPa).

5. Frequently Asked Questions (FAQ)

Q1: Why does boiling point change with altitude?
A: At higher altitudes, atmospheric pressure is lower, which reduces the energy needed for water molecules to escape into the vapor phase.

Q2: How accurate is this calculation?
A: The 1°C per 300 meters rule is an approximation. For precise calculations, specific atmospheric pressure measurements are needed.

Q3: Does humidity affect boiling point?
A: Humidity has a minimal effect on boiling point compared to atmospheric pressure changes.

Q4: What's the boiling point at extreme altitudes?
A: At Mount Everest's summit (8,848 m), water boils at about 68°C, making it difficult to cook food properly.

Q5: How does pressure cooking affect boiling point?
A: Pressure cookers increase the internal pressure, raising the boiling point and allowing food to cook faster.
