What is the freezing point of water in degrees Celsius?

• A. -32°C
• B. 0°C
• C. 100°C
• D. 32°C

Answer: (B)

The freezing point of water is defined as the temperature at which liquid water changes into ice under standard atmospheric pressure. This phase change occurs at 0 degrees Celsius. This value is a key reference point on the Celsius temperature scale, which is based on the properties of water. Understanding this freezing point is crucial in various scientific and everyday contexts, such as weather conditions, cooking, and the study of materials. For instance, knowing that water freezes at 0°C can help individuals understand when to expect snow or ice during cold weather. Additionally, this knowledge is essential in various scientific experiments and processes that involve temperature control. The other provided temperatures do not represent the freezing point of water. For example, -32°C is well below freezing, while 100°C is the boiling point of water. The temperature of 32°F (which converts to 0°C) is often confused with freezing due to its equivalence in the Fahrenheit scale, but on the Celsius scale, the correct answer remains 0°C.
