Why do farmers fill their fields with water on a cold winter night?

1.	Why do farmers fill their fields with water on a cold winter night?
Answer» 1. In the absence of water, if on a cold winter night, the atmospheric temperature falls below 0°C, the water in the fine capillaries of plants will freeze, so the veins will burst due to the increase in volume of water on freezing. 2. As a result, plants will die and the crop will be destroyed. 3. In order to save crop on such cold nights, farmers fill their field with water because water has high specific heat, so it does not allow the temperature in the plants of surrounding area to fall up to 0°C.
