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, try these conceptual questions.

convert thermal energy into mechanical energy
lead to a more ordered state
cannot be reversed
do not conserve energy
