Cube A has more thermal energy than cube B.
Explanation:
It is obvious that cube A has gained more thermal energy compared to cube B.
From the description of the experiment, both cubes had the same temperature which is 50°C. Temperature is the degree of hotness or coldness of a body.
Thermal energy is a form of energy expressed as heat in a body.
Cube A has a higher volume because it has gained more thermal energy than Cube B.
Thermal energy increases the rate of vibration of atoms in the crystal lattice of the solid. The more the thermal energy, the more the vibration. This is why Cube A has expanded so much and changed volume.

Answer:
NaNO3.
Explanation:
The Na ion has one positive charge and the NO3 ion has one negative charge so the correct formula is NaNO3.
First, when the student added the layers of wax over each other, this became a representation of sedimentary rocks.
Then the student folded his/her palm and squeezed the layers of wax. This means that the student applied heat and pressure on the wax (sedimentary rocks)
Referring to the diagram below which represents the rock cycle, we will find that applying heat and pressure on sedimentary rocks would convert these rocks into metamorphic rocks.
Based on the above, the best choice would be:<span>d. Heat and pressure can change sedimentary rocks into metamorphic rocks.</span>
the action and reaction do not lead equilibrium if action and reaction force react on different objects
