A cube of iron at 20. Degrees C is placed in contact with a cube of copper at 60 degrees C. Which statement describes the initial flow of heat between the cubes?

D) Heat flows from the copper cube to the iron cube.

Explanation:

These are the options for the question

A) Heat does not flow between the cubes.

B) Heat flows in both directions between the cubes

C) Heat flows from the iron cube into the copper cube.

D) Heat flows from the copper cube to the iron cube.

From the knowledge of

second law of Thermodynamicss, which says heat moved from higher temperature to lower temperature region, and termal conduction,energy such as heat will only flow from higher temperature to lower temperature, which means the heat will move from higher concentration to lower Concentration. As the cube of copper at 60 degrees is heated the atoms beginnings to vibrate as it acquire energy then moves and flow to the lower temperature part.

Therefore, Heat flows from the copper cube to the iron cube.
