How do ocean currents affect the coastal regions of S.America at 20 degrees south latitude

When a lake freezes over. How does the energy content of the lake change?

Respuesta :

Answer:

Explanation:The remaining air (air that does not descend at 30 degrees North or South latitude) continues toward the poles and is known as the westerly winds, or westerlies

Question: How do ocean currents affect the coastal regions of S.America at 20 degrees south latitude

Answer: Warm and cold ocean currents can affect the climate of an area along the coast if the winds blow in from the ocean. Warm ocean currents heat the air above the water and carry the warm air to the land, increasing the temperature of the coastal region

Question: When a lake freezes over. How does the energy content of the lake change?

Answer: Liquid water has more energy than frozen water. When water freezes it gives up some of the water's energy. This energy that is given up is the latent heat of freezing. When the water was freezing latent heat of freezing energy was being released

(WATER IS THE LAKE)

Bonus: I know that during melting, there is no temperature change as the heat energy is used to do work against potential bond energy but why doesn't temperature change when freezing? Freezing is the opposite process of melting. If the temperature does not increase as the ice melts, the temperature will not decrease as water freezes. Melting and freezing are entropy changes. Entropy measure the amount of disorder in a system. A system, like ice, which has less freedom of motion, has less disorder. A system, like liquid water, which has more freedom of motion, has more disorder. So water has more entropy than ice. Ice is a very ordered arrangement of H2O molecules in a crystalline form. As heat energy is added to ice, the energy is used the break the bonds between the H2O molecules in the ice crystals. So, the temperature remains constant. You might say that the energy that is added to the ice is used to increase the entropy of the system, instead of increasing the temperature of the system.
