Question

In agricultural areas, farmers pay close attention to the weather forecast. Right before a predicted overnight freeze, farmers spray water on crops to protect the plants. Use the properties of water to explain how this method works. Be sure to mention why hydrogen bonds are responsible for this phenomenon.

Answer 1

The things with winter and overnight freeze are that this change of the weather can seriously harm the crop and do irreversible damage.

To prevent this, farmers use some methods.

One is the usage of heaters, not allowing the freeze to set.

Another one is to spray the crop with water before the predicted overnight freeze. When water freezes and turns into ice, it releases latent heat. Then, the ice that builds upon the plant will insulate it from the colder surrounding air temperatures.
