Boiling Temperature Equation:
| From: | To: |
The boiling temperature equation calculates the temperature at which water boils 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 altitude affects boiling temperature is crucial for cooking, scientific experiments, and various industrial processes where precise temperature control is required.
Tips: Enter altitude in meters. The value must be a non-negative number representing the elevation above sea level.
Q1: Why does boiling point 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: This equation provides a good approximation for most practical purposes, though more complex formulas exist for precise scientific calculations that account for humidity and other factors.
Q3: Does this apply to other liquids?
A: While all liquids experience boiling point depression with decreased pressure, the specific rate of change varies for different substances.
Q4: What's the boiling point at extreme altitudes?
A: At very high altitudes (e.g., Mount Everest at 8,848m), water boils at around 68°C, which significantly affects cooking times and food preparation.
Q5: How does this affect cooking?
A: At higher altitudes, foods take longer to cook because the lower boiling temperature reduces the heat transfer efficiency, and leavening gases in baked goods expand more quickly.
