1. What is the Boiling Point of Water?

The boiling point of water is the temperature at which water changes from liquid to vapor phase. At standard atmospheric pressure (1 atm), pure water boils at 100°C.

2. How Does the Calculator Work?

The calculator uses the standard boiling point equation:

Where:

• \( T_b \) — Boiling point temperature (°C)

Explanation: This simplified calculation provides the standard boiling point of water at normal atmospheric conditions.

3. Importance of Boiling Point Calculation

Details: Understanding water's boiling point is essential for cooking, scientific experiments, industrial processes, and various technical applications where phase changes are critical.

4. Using the Calculator

Tips: Enter atmospheric pressure in atm. The calculator will provide the boiling point of water at the specified pressure conditions.

5. Frequently Asked Questions (FAQ)

Q1: Why does water boil at 100°C?
A: At standard atmospheric pressure (1 atm), water reaches its vapor pressure equal to atmospheric pressure at 100°C, causing it to boil.

Q2: How does altitude affect boiling point?
A: At higher altitudes with lower atmospheric pressure, water boils at lower temperatures due to decreased air pressure.

Q3: Does purity affect boiling point?
A: Yes, impurities and dissolved substances can elevate the boiling point of water through boiling point elevation.

Q4: What is the boiling point at different pressures?
A: Boiling point decreases with decreasing pressure and increases with increasing pressure following specific thermodynamic relationships.

Q5: Why is this important for cooking?
A: Understanding boiling points helps in proper cooking techniques, especially at high altitudes where cooking times may need adjustment.
