Applications of water's high specific heat capacity?

Answer 1

In cold countries, agricultural fields are watered during evenings. When atmosphere cools, this water also gets cooled. Then more heat is liberated. Thus this heat protects the seeds and plants from getting freezed. Water is used in the radiators of vehicles. Even though water receives a lot of heat from the engine, because of it's high specific heat capacity the water doesn't get heated fast.

Answer 2

1. Fomentation:

Hot water bottles are used for fomentation, as the water remains hot in the bottle for a long time in spite of giving off large quantities of heat.

2. Car radiators:

Water is used as coolant car radiators. Due to its high specific heat capacity, it can absorb a large amount of heat energy from the engine of the car, but its temperature does not rise too high.

3. Bottled Wines:

In cold countries, wine bottles re kept under water. Due to the high specific heat capacity of water, it takes a long time for the temperature to fall to 00 C.

4. Land and sea breezes:

The specific heat capacity of water is about five times more than that of sand. It therefore, takes a much longer time to heat and to cool with respect to sand.

During the day, the land cools faster than the sea. The hot air from the sea rises while the cool air from the sea moves to take its place, giving rise to a sea breeze.

During the night, the land cools faster than the sea. The hot air from the land moves to take its place, giving rise to a land breeze.

5. Cooking utensilsCooking utensils are made of metal which has low specific heat capacity so that it need less heat to raise up the temperature.

Handles of cooking utensils are made of substances with high specific heat capacities so that its temperature won't become too high even if it absorbs large amount of heat.

6.

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.
