Question

Sunlight hits the water at the top of a swimming pool. How is heat energy transferred from the top to the bottom of the pool?

Answer 1

Answer:

Between the surface water and the bottom of the pool, the transfer of thermal energy is done by conduction.

Explanation:

The waters on the surface of the pool receive thermal energy from the sun, through the irradiation process. However, when we enter the pool, we realize that the waters at the bottom of the pool are colder than the waters on the surface. This is because the hot water is less dense, that is, lighter than cold water, so the water on the surface of the pool that has been heated by the sun, cannot descend to the bottom of the pool and transfer thermal energy through the process. convection.

In this case, the transfer of thermal energy in the waters of the pool is taking place through the conduction process. Although this process is associated with solid materials, it occurs in the pools very slowly. This process occurs when the heat of the sun heats the water atoms on the surface of the pool, causing these atoms to become agitated and start to bump into each other, transferring heat to each other each time they touch each other. This transfer happens from the surface to the bottom of the pool.
