Specific heat capacity (Water)

Dear student
 
Please post each query seperately.
 
 
Water is often used to cool the radiators of the engines in motorcars and trucks etc. as it can draw a large amount of heat without much rise in its own temperature.
 
 
The specific heat capacity of water is very high i.e. 4200 J kg-1 Co . It is about 5 times as high as that of sand. So water takes a a very long time to get heated up and an equally long time to get cooled. Thus, there is a large difference in temperature between the land and the sea due to which land and sea breezes are formed.
We hope this clarifies your doubt.
