Question

aluminum at 20 °c water at 75 °c which direction will heat energy transfer in this system? from the water to the aluminum from the aluminum to the water back and forth between the aluminum and the water

Explanation:

Heat energy transfers from a higher - temperature object to a lower - temperature object. The water has a temperature of \(75^{\circ}\text{C}\) and the aluminum has a temperature of \(20^{\circ}\text{C}\). Since the water is at a higher temperature than the aluminum, heat will transfer from the water to the aluminum until thermal equilibrium is reached.

Answer:

from the water to the aluminum
