Because coastal cities are close to the sea, according to physics, the specific heat capacity of water is greater than that of sand or soil, and the heat emitted by the sun during the same period of time is certain, so the heat absorbed by the earth is also the same.
From the formula, it can be seen that the heat-absorbing temperature must increase (or decrease) in inverse proportion to the specific heat capacity. The specific heat capacity of water is large, so the temperature drops. slowly, so the temperature in coastal cities is higher at night than in inland cities.
Detailed information:
Water has a large specific heat capacity and is used in industrial applications. and agricultural production and daily life. It has a wide range of applications in life. This application considers mainThere are two aspects: the first is that a certain mass of water absorbs (or releases) a lot of heat without changing its own temperature too much, which is conducive to climate regulation; the second is that a certain mass of water increases; (or decreases). A certain temperature absorbs (or releases) a lot of heat, which is beneficial for using water as a coolant or for heating.
Water has a high specific heat capacity and has a significant impact on climate change. Under the same heating or cooling conditions, the water temperature changes little. This water characteristic has a great influence on the climate. During the day, the temperature of coastal areas increases more slowly than that of inland areas. coastal areas decrease less at night. For this reason, the temperature of coastal areas during the day Changes are small, but the temperature inside tThe weather changes considerably during the summer.
Winter inland is colder than along the coast. When the ambient temperature changes quickly, the water temperature changes relatively slowly. The high proportion of water in an organism helps regulate its own temperature so that the temperature does not change too quickly and cause serious damage to the organism. The reasons for the formation of sea and land breezes are similar.
