Jack's model includes one object consisting of two molecules and one object consisting of six molecules. He put 16 energy cubes in each object and stated that his model showed the two objects at equilibrium.

Explain what is wrong with Jack's model.

the molecules have different energy and the system is not in equilibrium

Explanation:

The model developed by Jack has the same energy for each of the two objects, but as each object is made up of a different number of molecules, in the system with more molecules, object 2, each one has approximately 2.4 less energy and the molecules of Object 1 have an E / 2 energy.

So when you book them together the molecules have different energy and the system is not in equilibrium
