Solution : Second law of thermodynamics can be stated as : Kelvin's statement: It is impossible to get a continuous supply of work from a body by cooling it to a temperature lower than that of its surroundings.
The second law of thermodynamics is a physical law based on universal experience concerning heat and energy interconversions. One simple statement of the law is that heat always moves from hotter objects to colder objects (or "downhill"), unless energy in some form is supplied to reverse the direction of heat flow. Another definition is: "Not all heat energy can be converted into work WebThe Second Law of Thermodynamics states that the state of entropy of the entire universe, as an isolated system, will always increase over time.
