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 statements in the following list all refer to thermodynamics and entropy. Check the boxes of the THREE CORRECT statements. 1. Entropy is similar to energy and obeys a conservation law. 2. In an adiabatic process the change in the internal energy of the gas is the same as the work done on the gas. 3. An ideal gas undergoes a reversible process whereby the pressure of the gas decreases by a factor of 3 but its volume increases by...
