Learning outcomes - after studying this topic, you should be able to:

• define entropy in terms of the tendency of energy to spread out
• predict how entropy changes with the physical state, the temperature, the size of the molecule and the complexity of a molecule
• predict whether entropy increases or decreases for simple physical and chemical changes, especially for changes in physical state
• apply entropy concept qualitatively to predict the direction of phase changes

• Sections 7.3 and 8.4 (in Blackman, Bottle, Schmid, Mocerino and Wille, Chemistry, 3^rd Edition, 2015 (John Wiley))

• The second law of thermodynamics (in Wikibooks General Chemistry)
