- ‘Consequently entropy is a state function.’
- ‘A state function is a property of a system that does not depend on pathways, only on the initial and final states.’
- ‘The second law defines a new state function known as the entropy.’
- ‘However, heat and work are not state functions and their values are affects by the pathway taken.’
