AP Chemistry Unit 5 Notes Chapter 6 Section 1: The Nature of Energy Energy- Law of conservation of energy- Potential Energy – Kinetic energy- What happens to energy that is “lost”? What are 2 ways to transfer energy? Heat- Work- Pathway- o Energy change is independent of the pathway; however, work and heat are both dependent on the pathway. o State function- a property of the system that depends only on o State function: energy. Work and heat are NOT state functions System- Surroundings- Exothermic- Endothermic- Where does the energy come from in an exothermic reaction? Where does the absorbed energy go in an endothermic reaction? Thermodynamics- o First law- energy of the universe is constant o Internal Energy- What does the sign in a thermodynamic quantity indicate? o Same conventions apply to work. If work is done on the system- energy flows into the system, then w is positive. If work is done by the system- energy flows out of the system, then w is negative
