consequences of high specific heat capacity of water
Answers
Hey! Here is your ans.
i)Moderate climate of sea shore: The specific heat capacity of water is equal to 4200 J Kg-1 K-1. It is ab out five times of that of sand. Hence, the heat energy required for same rise in temperature will be much more for water than sand or land. Hence, the land gets heated much more easily then water. Also, it cools down much easily. Hence, a large difference in temperature is formed that gives rise to land breeze and sea breeze. It keeps the climate of the coastal areas moderate. Monsoon in India is also due to the difference in temperature between the land and the surrounding sea.
ii)Fomentation: Water is used in hot water bottles for fomentation as the water can absorb a large amount of water without much rise in temperature. Hence, the patient can get relief at 500C of water.Also, it does not cools down easily.
iii)Protection of crops: Farmers generally fill their field with water during winter season at night to protect the crops from frost. In the absence of water, if on a cold night the temperature of the surroundings fall below 00C, then the veins of the plants shall freeze. Due to anomalous expansion of water, ice shall occupy more volume than water. as a result of this expansion, veins shall burst and crops shall be destroyed. But water sprinkled on the crops shall not allow the temperature of the veins to fall below 00C.
iv)Used as a reservoir: In cold countries, water is used as a reservoir for wine and juice to avoid their freezing. The reason is that water can provide more heat to the bottles due to its high specific heat capacity. Hence, they do not cool down further to freeze.
v)As a coolant : Water is used as a effective coolant. By allowing water to flow in radiator pipes of the vehicles, heat energy form such parts is removed. Thus, water extracts much heat without much rise in temperature.
