Test and analysis: according to the characteristics of large specific heat capacity of water, analyze why the temperature difference between day and night in coastal cities is small, and then make a judgment.
There is more water in coastal areas, and the specific heat capacity of water is greater. During the day, compared with the quality of water and gravel, the absorbed heat is the same, and the temperature of water rises less. At night, the same heat is released, and the water temperature drops less, making the temperature difference between day and night in coastal areas small. As can be seen from the table, the temperature difference in city A is small, so city A is a coastal city in Shanghai. The temperature difference of B is large, and B is the inland city of Xi 'an.
Comments: Understanding the characteristics and application of water with large specific heat capacity in this question, and using the physical knowledge learned to explain the phenomena in life are the hot spots in the senior high school entrance examination.
