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
