How does specific heat affect temp
WebThe heating and cooling differences of land and water affect the temperature and movement of air masses above the land and water. Because water has a much higher heat capacity, or specific heat, than do sands, soils or other materials, for a given amount of solar irradiation (insolation), water temperature will increase less than land temperature. WebSpecific heat capacity is the heat needed to raise a substance’s temperature by 1 degree Celsius. Similarly, heat capacity is the ratio between the energy provided to a substance and the corresponding …
