Second law of thermodynamics:
Second law of thermodynamics is also known as degradation of energy.
As per Kelvin law plank constant statement of second law of thermodynamics can be given as to construct a heat engine which would convert all the heat energy into work by interacting which is single heat reservoir a heat engine requires two reservoirs his one at Higher temperature and another at lower temperature to convert heat energy.The heat can be supplied to the higher temperature without any external work it is simply related to surroundings without doing any external work second law of the basics for all the information it is also known as degradation of energy.
