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.

Verified step by step guidance

1. Understand the unique properties of water, particularly its high specific heat capacity and heat of fusion. Water's high specific heat capacity means it can absorb a lot of heat before it changes temperature, and its high heat of fusion means it requires a lot of energy to change from liquid to solid (freeze).
2. Recognize that when water is sprayed on the crops and it begins to freeze, the process of freezing actually releases heat into the surrounding environment. This released heat is known as the latent heat of fusion.
3. Acknowledge that the heat released during the freezing process helps to keep the plants and the surrounding air slightly warmer than they would be otherwise, which can protect the plants from damage due to freezing temperatures.
4. Explain the role of hydrogen bonds in water's properties. Hydrogen bonds make ice less dense than liquid water and contribute to the high specific heat and heat of fusion. These bonds require a lot of energy to break, which is why water releases a significant amount of heat when it freezes.
5. Summarize how the application of water before a freeze can create a protective ice layer that insulates the plant, slowing down the loss of heat from the plant to the environment and preventing internal temperatures of the plants from dropping too low, thus avoiding frost damage.
