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), water boils at 100°C (212°F).

2. How Does the Calculator Work?

The calculator uses the standard boiling point value:

Where:

• \( T_b \) — Boiling point temperature (°C)
• Standard value at 1 atmosphere pressure

Explanation: This calculator provides the standard boiling point of water at atmospheric pressure. The boiling point changes with pressure variations.

3. Importance of Boiling Point Calculation

Details: Knowing the boiling point of water is essential for cooking, chemical processes, laboratory work, and various industrial applications where temperature control is critical.

4. Using the Calculator

Tips: Enter atmospheric pressure in atm (standard is 1 atm). The calculator will display the standard boiling point of water at that pressure.

5. Frequently Asked Questions (FAQ)

Q1: Why does water boil at 100°C at sea level?
A: At standard atmospheric pressure (1 atm), water molecules have enough energy to overcome atmospheric pressure and transition to vapor at 100°C.

Q2: How does altitude affect boiling point?
A: At higher altitudes with lower atmospheric pressure, water boils at lower temperatures (approximately 1°C lower per 300 meters of altitude).

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

Q4: What is the boiling point in Fahrenheit?
A: The standard boiling point of water is 212°F at 1 atmosphere pressure.

Q5: Does the calculator account for pressure variations?
A: This calculator provides the standard value. For precise calculations at different pressures, more complex equations would be needed.
