Energy Review & Systems Notes

Energy = the ability to do work or transfer heat Kinetic Energy = moving energy Ex: wind, heat, electromagnetic radiation Potential Energy = stored energy Unlit match, nuclear energy stored in nuclei of atoms, chemical energy (energy in food)

Kinetic vs. Potential Energy

Laws of Thermodynamics 1st law: Energy cannot be created or destroyed, it can only change form! 2nd Law: When energy changes form, it loses quality; usually in the form of heat

Energy Quality High quality energy – concentrated; high capacity to do useful work Nuclear fission, burning coal, gasoline Low quality energy – dispersed; little capacity to do useful work Heat of the ocean, burning wood

The main goal of thermoDynamics Is to follow energy flowing from one place to another during chemical or physical changes To determine the quantity of heat exchanged between a system and its surroundings. System: Part of the universe being studied (usually a chemical reaction) Surroundings: The rest of the universe that interacts with the system

What are systems and how do they respond to change? Open system: exchanges of matter and energy occur across boundaries Closed system: No matter and energy exchanges across boundaries (occur way less) Inputs: additions to a system Outputs: losses from a system

System Analysis Determine the inputs and outputs of a system and evaluate change Steady state: when inputs = outputs so the system isn’t changing

Endothermic vs. Exothermic endothermic reaction: energy is absorbed from the surroundings in the form of heat. exothermic reaction: energy is released from the system into the surroundings.
