• Energy can be transferred between different forms (e.g. heat, work)

• The total energy of a system remains constant

The second law of thermodynamics states that the total entropy of an isolated system can never decrease over time.

• Entropy tends to increase in a closed system

• Heat energy naturally flows from hot to cold objects
