Water Boiling Temperature Equation:
| From: | To: |
The water boiling temperature equation calculates how the boiling point of water decreases with increasing altitude. At higher elevations, atmospheric pressure decreases, which lowers the temperature at which water boils.
The calculator uses the water boiling temperature equation:
Where:
Explanation: The equation shows that for every meter increase in altitude, the boiling point of water decreases by approximately 0.0033°C from the standard boiling point of 100°C at sea level.
Details: Understanding how altitude affects boiling temperature is crucial for cooking, scientific experiments, and various industrial processes. At high altitudes, foods take longer to cook because water boils at a lower temperature.
Tips: Enter altitude in meters above sea level. The calculator will determine the approximate boiling point of water at that elevation.
Q1: Why does water boil at lower temperatures at higher altitudes?
A: Atmospheric pressure decreases with altitude, which reduces the energy needed for water molecules to escape into the vapor phase, thus lowering the boiling point.
Q2: How accurate is this calculation?
A: This provides a good approximation for most practical purposes, though actual boiling point can vary slightly with weather conditions and atmospheric pressure changes.
Q3: Does this affect cooking times?
A: Yes, at higher altitudes where water boils at lower temperatures, cooking times generally need to be increased as heat transfer is less efficient.
Q4: What's the boiling point at extreme altitudes?
A: At the summit of Mount Everest (8,848 meters), water boils at approximately 71°C, making it difficult to cook food properly.
Q5: Are there more precise formulas available?
A: Yes, more complex formulas exist that account for humidity and precise atmospheric pressure, but this simplified equation works well for most applications.
