Ans: Second law of thermodynamics means second equation in thermodynamics and it is expressed in terms of entropy(it means a thermodynamic quantity of a system's thermal energy for conversion into mechanical work).Second law of thermodynamics states that heat cannot suddenly flow from a cold object to a hot object in a closed system as it may violate the equation.It also states that the change in entropy in the whole universe can never be negative.

Second Law of Thermodynamics Learning Goal: To understand the implications of the second law of thermodynamics. The second law of thermodynamics explains the direction in which the thermodynamic processes tend to go. That is, it limits the types of final states of the system that naturally evolve from a given initial state. The second law has many practical applications. For example it explains the limits of efficiency for heat engines and refrigerators. To develop a better understanding of this law,...

The second law of thermodynamics states that the entropy of a closed system always increases. Cellular systems take disordered substrates to construct highly ordered molecules and organelles. How can photosynthesis be used to make glucose without violating this law? Note: glucose is more a ordered molecule then the CO2 used to construct it.
