Answer:
Gravitational potential energy may be converted to other forms of energy, such as kinetic energy. If we release the mass, gravitational force will do an amount of work equal to mgh on it, thereby increasing its kinetic energy by that same amount (by the work-energy theorem).
Explanation:
Heat; rather, or change of the molecules to make them move faster
Given what we know, we can confirm that the best way to prove that no mass was lost during the reaction would be to follow option C and determine the masses of all substances before and after the reaction.
<h3>Why is this the best method?</h3>
This method provides two sets of data in order to draw a comparison. The other option will either not produce comparable data, or do not take into account all of the elements being produced.
Therefore, by comparing the mass of baking soda and vinegar before the reaction to the mass of carbon dioxide and water after the reaction, we can analyze the differences if any, and confirm that no mass was lost during the reaction.
