The weather in Fuding is good

(1) The summer in fuding city is the longest year with high temperature on record, with the temperature exceeding 34℃ for more than half a month. Many people choose to go to places with plenty of water, such as the seaside, to escape the summer. This is because under the same heating conditions, because of the large specific heat capacity of water, the temperature of water rises slowly, that is, the relative temperature is low and relatively cool.

Xiaoming followed his parents to the seaside. When he stepped barefoot on the beach and sea water, he found that the sand was hot and the sea water was cold, which had nothing to do with their mass and the surface area of the sun, but with the specific heat capacity of the object. The specific heat capacity of water is large, and it absorbs the same heat under the same sunshine conditions, so the temperature change of water is small and the temperature change of sand is large, so the seawater is cold and the sand is hot.

So the answer is: the specific heat capacity of water is the largest; Water has a large specific heat capacity. Under the same sunshine condition and absorbing the same heat, the temperature of water changes little, while the temperature of sand changes greatly, so the sea water is cool and the sand is hot.
