Answer:

Water has a boiling point of 212 °F, or 100 °C (100 degrees Celsius).

The boiling point of water in Celsius is 100°C at standard atmospheric pressure (1 atmosphere or 101.3 kPa).

Why Water Boils at 100°C:

  • Standard Atmospheric Pressure - At sea level, the atmospheric pressure is standard (1 atmosphere), and under these conditions, water boils at 100°C. The boiling point is the temperature at which the vapor pressure of the liquid equals the external pressure surrounding the liquid.
  • Intermolecular Forces - Water has strong hydrogen bonds between its molecules, requiring a significant amount of energy (heat) to break these bonds and transition from the liquid to the gas phase.

Importance of the Boiling Point of Water:

  • Scientific Reference - The boiling point of water at 100°C is a fundamental reference point in thermodynamics and various scientific calculations.
  • Cooking and Food Safety - Knowing the boiling point of water is essential for cooking and food preparation. Boiling water is a common method for sterilizing and making food safe by killing harmful microorganisms.
  • Industrial Applications - The boiling point of water is critical in industrial processes, such as in the operation of steam engines, power plants, and heating systems. It helps in designing equipment and managing thermal systems efficiently.
