Due to the deterioration of the environment, the phenomenon of global warming is becoming more and more obvious. This summer in fuding city is the longest year with high temperature on record, lasting more than half a month.

(1) fuding city's summer is the longest year with high temperature since records began, with the temperature exceeding 34℃ for more than half a month. Many people choose to go to places with more water, such as the seaside, to escape the heat. This is because under the same heating condition, because of the large specific heat capacity of water, the temperature of water changes little, so the temperature of the seaside rises slowly, that is, the relative temperature is low and relatively cool.

(2) Xiao Ming also 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 quality and sun surface area, but with the specific heat of the object. The specific heat of water was large, and under the same sunshine conditions, the temperature of water changed little, but the temperature of sand changed greatly, so the sea water was cold and the sand was hot. < p The specific heat capacity of water is large. Under the same sunshine condition, it absorbs the same heat, and the temperature of water changes little, but the temperature of sand changes greatly, so the sea water is cool and the sand is hot.
