Imagine a day of sunny summer and you are walking on the road then you are realize the importance of your AC and say thanks to your AC. Air  conditioner work on interesting technology to keep our room chilled. it use some physical laws of thermodynamics to removing heat from the air inside the room. Air conditioner Photo Credit : coolingcitycenter.in Air Conditioner work efficiently to cool the indoor air quickly, but it consume more electric power to do their job. its work under the basic physical laws which says 'the heat is absorbed during the phase transfer of the refrigerant material. Phase Conversion   : the physical state of the material is changes by absorbing the heat from outside atmosphere by virtue of temperature difference between them. this change in physical state by absorbing heat is called the phase conversation or phase transformation.   Example  :  the piece of ice melt on your palm by absorbing heat from you body, absorbed heat doesn't increas
