Compare mechanical energy and thermal
energy.

Explanation:

Mechanical and thermal energy are both different forms of energy. They can be converted from one to another. Some systems relies solely on this form of energy conversion  between these types of interactions.

Mechanical energy is a form of energy that is due to the motion of a body.

Thermal energy is due to the temperature changes between bodies.

Both forms of energy are not related but they can be converted from one from to anther.

in chemistry, a solution’s concentration is how much of a dissolvable substance, known as a solute, is mixed with another substance, called the solvent. the standard formula is c = m/v, where c is the concentration, m is the mass of the solute dissolved, and v is the total volume
