Detailed explanation-1: -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-2: -At temperatures below 32°F (0°C), liquid water freezes; 32°F (0°C) is the freezing point of water. At temperatures above 32°F (0°C), pure water ice melts and changes state from a solid to a liquid (water); 32°F (0°C) is the melting point.
Detailed explanation-3: -At 0°C the physical state of water is solid(ice), because a phase change process takes place at 0°C. If you remove heat from water which is at 0°C then you will get 0°C ice first . It is because 0°C is the freezing point of water.
