Introduction:
The measurement of energy can be done by studying its effects on the matter. It is basically the ability to do perform a task. The kinetic, as well as potential work capacities, are exhibited by every form of energy. The energy can neither be created nor be destroyed. It can just change from one form to another.
Answer to Problem 1MC
Correct answer:
The energy can move matter and so, it can be kinetic. The potential energy that is stored in the
Explanation of Solution
Justification for the correct answer:
Option (b) is given that kinetic energy can move matter. When the work is actually done by the energy, it is called the kinetic energy. The movement of all form of substances is possible due to the kinetic energy. Hence, option (b) is correct.
Option (c) is given that potential energy that is stored in the chemical bonds is known as chemical energy. The energy in an inactive form or the stored form is termed as potential energy. Thus, the energy in the chemical bonds is a stored form of energy and is called potential energy. The breaking up of these bonds release the potential energy in the form of kinetic energy. Hence, option (c) is correct.
Option (e) is given that the electromagnetic waves are involved in the radiant energy. The energy that travels in the form of waves is known as radiant energy. The energy of the electromagnetic spectrum that comprises infrared radiation, X rays, radio waves, ultraviolet waves, and visible light travel in the form of waves and thus are involved in the radiant energy. Hence, option (e) is correct.
Explanation for the incorrect answers:
Option (a) is given that energy occupies space and has mass. It is the matter and not the energy that occupies space and has mass. So, it is an incorrect option.
Option (d) is given that in moving the matter, the mechanical energy is indirectly involved. However, the mechanical energy is directly associated with the movement of the matter. For example, the movement of the bicycle is possible with the help of mechanical energy provided by the legs. So, it is an incorrect option.
Hence, options (a) and (d) are incorrect.
Therefore, it can be concluded that the stored form of energy is potential energy while the moving form is kinetic energy. The radiant energy includes the electromagnetic waves like visible light, infrared, radio waves, and many more electromagnetic radiations.
