Answer:

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

Step-by-step explanation:

The reason comes from the second law of thermodynamics:

Heat energy will flow spontaneously from an area of high temperature to one of low temperature.

When you bring two objects of different temperature into contact, heat energy always moves from the hotter to the cooler object.

The copper cube is hotter than the iron, so heat flows from the copper cube to the iron cube.

The statement that describes the initial flow of heat between the cubes is Option(D) Heat flows from the copper cube to the iron cube.

What is Second Law of Thermodynamics ?

According to the Second Law of Thermodynamics, when two objects of different material and different temperature is brought into contact together then heat always flow from object at higher temperature to the object at lower temperature.

What statement describes the flow of heat between the cubes ?

It is given that a cube of iron at 20.°C is placed in contact with a cube of copper at 60.°C.

The possible hypothesis is it is only possible for any process to have as its sole result of heat transfer from hotter to cooler object .

Thus, the statement that describes the initial flow of heat between the cubes is Option(D) Heat flows from the copper cube to the iron cube.
