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...
