<u>Answer:</u>
<em>The law of conservation of energy remains the same for any kind of chemical or physical energy. Since that happens inside laboratory or outside it anywhere in the nature.</em>
<u>Explanation:</u>
Any example that will be considered will demonstrate <em>no change in ultimate mass and any kind of energy</em> that is involved in the reaction can only change the form of its nature while the total energy remains conserved.
There can be <em>no gain or loss in mass or energy</em> in any reaction that takes place reactant and product and energy should remain same.
<em>For example rolling balls force </em>with which it is thrown the distance reached by the ball would depend on the frictional energy and air resistance acting on it and on considering these forces it shall remain equal to the original source.
