Understanding Water Boiling Point
Water boils at a specific temperature depending on the scale used to measure temperature. In the Celsius scale, water boils at 100°C.
Why Does Water Boil at 100°C?
- Boiling Point Definition: The boiling point of a liquid is the temperature at which it changes from a liquid to a gas. For water, this occurs when it reaches 100°C at standard atmospheric pressure (1 atmosphere or 101.3 kPa).
- Molecular Activity: At this temperature, water molecules have enough energy to overcome the forces holding them together in the liquid state. As they gain energy, they move faster and eventually break free to become steam (gas).
Comparison with Other Temperatures
- 0°C: This is the freezing point of water, where it changes from liquid to solid.
- 32°C: This is equivalent to 0°C in the Fahrenheit scale, not relevant for boiling.
- 273°C: This temperature is not standard for boiling water; it relates to absolute zero in Kelvin.
Conclusion
In summary, the correct answer to the question regarding the boiling point of water on the Celsius scale is 100°C. This is a fundamental concept in understanding phase changes in water, which is crucial for various scientific and practical applications.
