1. a cube of iron at 20.°c is placed in contact with a cube of copper at 60.°c. which statement describes the initial flow of heat between the cubes?

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.

here hope this helps

the atomic number will stay the same no matter how many electrons it has, so it doesn’t decrease nor increase. it’ll only change with a different number of protons

catya your not at all which answer i've seen you do this on another question!
