We cannot image the life without electricity. *Evaporation - the formation of clouds in nature is based on the physical phenomenon. *Physics is also applied in our body - due to electrical signals, which carry the sensation, to mind, we are able to see, listen or to feel the objects. In the cooking of the vegetables , some of the physical laws work. Even we choose the metal of the utensil on the behalf of physics. We generally use water as a coolant or as a heating liquid due to the high specific heat of water. Physics also explains the several form of energy and their transformation. Such as kinetic energy, potential energy, nuclear energy, etc. Even in the growing of plants the osmosis is used and the photosynthesis is used which is also explained by the physics. Physics gave us very important inventions such as cars, bikes, watche
