Question

Explain the energy changes taking place in the following situations.

Answer 1

The first picture shows how white light is broken into various wavelengths of the spectrum to show separate colored light rays.

The second picture shows fire which indicates the dissipation of heat energy through primarily radiation while the things directly in contact get high in temperature through conduction.

Reactions of oxidation also take place due to the combustion. The third picture shows hammering.

Here when the hammer is lifted its accumulation of potential energy, and when the hammer is the energy gets converted into kinetic energy.
