Boiling Temperature Equation:
| From: | To: |
The boiling temperature altitude equation calculates the boiling point of water at different altitudes. As altitude increases, atmospheric pressure decreases, which lowers the boiling point of water.
The calculator uses the 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 boiling temperature changes with altitude is crucial for cooking, scientific experiments, industrial processes, and various applications where precise temperature control is required.
Tips: Enter altitude in meters. The value must be non-negative (≥0). The calculator will compute the corresponding boiling temperature of water at that altitude.
Q1: Why does boiling temperature decrease with altitude?
A: As altitude increases, atmospheric pressure decreases. Since boiling occurs when vapor pressure equals atmospheric pressure, lower pressure means water boils at a lower temperature.
Q2: How accurate is this equation?
A: The equation provides a good approximation for most practical purposes, though actual values may vary slightly depending on local atmospheric conditions.
Q3: What is the boiling point at sea level?
A: At sea level (h = 0), the boiling point is exactly 100°C according to this equation.
Q4: Does this apply to other liquids?
A: While the principle applies to all liquids, the specific coefficients would be different. This equation is specifically for water.
Q5: How does this affect cooking times?
A: At higher altitudes where water boils at lower temperatures, cooking times generally need to be increased as the lower temperature is less effective at transferring heat to food.
