1. What is the Boiling Point Equation?

The boiling point equation calculates the boiling temperature of water at different altitudes. As altitude increases, atmospheric pressure decreases, which lowers the boiling point of water.

2. How Does the Calculator Work?

The calculator uses the boiling point equation:

Where:

• \( T_b \) — Boiling point of water (°C)
• \( h \) — Altitude above sea level (m)

Explanation: The equation shows that for every meter increase in altitude, the boiling point of water decreases by approximately 0.0033°C.

3. Importance of Boiling Point Calculation

Details: Understanding how boiling point changes with altitude is important for cooking, scientific experiments, and various industrial processes that involve boiling water at different elevations.

4. Using the Calculator

Tips: Enter altitude in meters above sea level. The value must be non-negative (≥0).

5. Frequently Asked Questions (FAQ)

Q1: Why does boiling point decrease with altitude?
A: As altitude increases, atmospheric pressure decreases. Since boiling occurs when vapor pressure equals atmospheric pressure, water boils at lower temperatures at higher altitudes.

Q2: How accurate is this equation?
A: This is a simplified approximation. The actual relationship is more complex and depends on various atmospheric conditions, but this equation provides a good estimate for most practical purposes.

Q3: What is the boiling point at sea level?
A: At sea level (h = 0), the boiling point is exactly 100°C, which is the standard boiling point of water.

Q4: Does this apply to other liquids?
A: No, this specific equation is only for water. Different liquids have different boiling points and different rates of change with altitude.

Q5: How does this affect cooking times?
A: At higher altitudes where water boils at lower temperatures, cooking times may need to be increased as the lower temperature is less effective at transferring heat to food.
