Question

In the 19th century James Joule, an English scientist, was the first to recognize the mechanical equivalent of heat as a specific form of the general rule of the conversion of one form of energy to another. Which fact can be explained with the help of this law?

Answer 1

Answer:

The law of conservation of energy is a law of science that states that energy cannot be created or destroyed, but only changed from one form into another or transferred from one object to another. This law is taught in physical science and physics classes in middle schools and high schools, and is used in those classes as well as in chemistry classes.

Explanation:

The law of conservation of energy can be seen in these everyday examples of energy transference:

Water can produce electricity. Water falls from the sky, converting potential energy to kinetic energy. This energy is then used to rotate the turbine of a generator to produce electricity. In this process, the potential energy of water in a dam can be turned into kinetic energy which can then become electric energy.
