Final answer:
The ocean remains cold in summer due to water's high specific heat capacity, which allows it to absorb large amounts of heat with minimal temperature change. the correct option is (a).
Step-by-step explanation:
The ocean is cold even in summer primarily because water has a high specific heat. Specific heat is the amount of heat energy required to raise the temperature of a substance by a certain amount. Water has a relatively high specific heat compared to many other substances, which means it can absorb and store a significant amount of heat without undergoing a large temperature change.
During the summer, the ocean absorbs heat from the sun, but due to its high specific heat, it warms up slowly. Additionally, water's ability to retain heat means that it releases heat slowly as well. As a result, the temperature of ocean water remains relatively cool, providing a contrast to the warmer temperatures experienced on land.
The ocean is cold even in summer because water has a high specific heat, which causes it to absorb and release heat slowly.
