Explanation:
The law of conservation of energy states that the total amount of energy in the universe remains constant; it cannot be created or destroyed. However, energy can change from one form to another. For example, potential energy can be converted into kinetic energy, chemical energy can be converted into thermal energy, and so on.
When energy changes forms, it may become available or unavailable to do work. This depends on the specific system and its constraints. Some energy transformations may result in energy becoming less available (for example, heat dissipation), while others may increase the availability of energy for work (such as converting thermal energy into mechanical energy).
Therefore, the availability of energy to do work varies tremendously as it constantly changes from one form to another.
