Boiling Point Equation:
| From: | To: |
The boiling point elevation equation calculates how the boiling point of water decreases with increasing elevation. At higher altitudes, atmospheric pressure decreases, which lowers the temperature at which water boils.
The calculator uses the boiling point equation:
Where:
Explanation: The equation shows that for every meter increase in elevation, 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 boiling point changes with elevation is crucial for cooking, scientific experiments, industrial processes, and any application where precise temperature control is important.
Tips: Enter elevation in meters above sea level. The value must be non-negative (≥0).
Q1: Why does boiling point decrease with elevation?
A: At higher elevations, atmospheric pressure is lower, which reduces the energy needed for water molecules to escape into the vapor phase.
Q2: How accurate is this equation?
A: This is a simplified approximation. The actual relationship is more complex and depends on additional atmospheric factors, but this equation provides a good estimate for most practical purposes.
Q3: Does this apply to other liquids besides water?
A: No, this specific equation is for water. Other liquids have different boiling point characteristics and would require different calculations.
Q4: What's the boiling point at extreme elevations?
A: At the summit of Mount Everest (8,848 m), water boils at approximately 71°C, which significantly affects cooking times and methods.
Q5: How does this affect cooking at high altitudes?
A: Lower boiling temperatures mean foods take longer to cook, and baking requires adjustments to recipes due to changes in leavening and evaporation rates.
