Detailed explanation-1: -Freezing point of water is 0∘C.
Detailed explanation-2: -We’ve all been taught that water freezes at 32 degrees Fahrenheit, 0 degrees Celsius, 273.15 Kelvin. That’s not always the case, though. Scientists have found liquid water as cold as-40 degrees F in clouds and even cooled water down to-42 degrees F in the lab.
Detailed explanation-3: -Ordinarily, the freezing point of water and melting point is 0 °C or 32 °F. The temperature may be lower if supercooling occurs or if there are impurities present in the water which could cause freezing point depression to occur.
Detailed explanation-4: -While the rule of thumb is that water freezes at 32 degrees Fahrenheit (0 degrees Celsius), water can actually stay liquid over a range of chilly temperatures under certain conditions.
Detailed explanation-5: -Water needs to be at the freezing temperature of 0°C or 32°F for it to freeze.
