Physics
Farmers fill their fields with water on a cold winter night. Explain in brief along with a reason.
Answer
On a cold winter night, if the atmospheric temperature falls below 0°C, water in the fine capillaries of plants will freeze, so the veins will burst due to the increase in volume of water on freezing. As a result, plants will die and the crop will get destroyed. In order to save crop on such cold nights, farmers fill their fields with water because water has a high specific heat capacity, so it does not allow the temperature in the surrounding area of plants to fall up to 0°C.
