The statement that it takes 80 times more energy for 0°C water to freeze than for 1°C water to cool to 0°C water is not accurate. In fact, the amount of energy required for water to freeze is relatively consistent regardless of whether it is at 0°C or slightly above.
Water freezes at 0°C (32°F) under normal atmospheric pressure. When water is at 1°C, it is already very close to its freezing point, and cooling it to 0°C does not require significantly more energy.
The reason water outside freezes easily at night is due to other factors such as the temperature of the surrounding environment and the loss of heat from the water to its surroundings. During the night, temperatures often drop below freezing point, causing the water to lose heat to the colder environment. This heat loss reduces the temperature of the water until it reaches its freezing point, leading to the formation of ice.
It's important to note that the statement you mentioned about the energy difference between freezing 0°C water and cooling 1°C water is not accurate. The energy required for the phase change from liquid to solid (freezing) is called the latent heat of fusion and remains constant regardless of the initial temperature of the water.
