Question

3°c cube 1
image of two touching cubes
6°c cube 2
which of the following correctly describes the flow of heat between the touching cubes?
the cubes will not transfer heat energy.
heat flows from cube 2 to cube 1.
heat flows from cube 1 to cube 2.

Explanation:

Heat transfer occurs from an object at a higher temperature to one at a lower temperature. Cube 2 is at \(6^\circ\text{C}\) (higher temperature) and Cube 1 is at \(3^\circ\text{C}\) (lower temperature). So heat flows from the warmer object (Cube 2) to the cooler object (Cube 1). The first option is wrong because there is a temperature difference, so heat will transfer. The third option is wrong as it reverses the direction of heat flow.

Answer:

B. Heat flows from cube 2 to cube 1. (assuming the middle option is labeled B; if the original options had different labels, adjust accordingly based on the correct direction of heat flow from higher to lower temperature)
