Energy Transformation & Laws of Thermodynamics Tuesday, February 7, 2017 2:26 PM
Electromagnetic Energy (light)
Photons = packets of electromagnetic energy, often called electromagnetic
- Photons behave like particles and like waves
- Types of electromagnetic energy (visible, IR, UV, radio waves) - Distinguished by energy, wavelength and frequency (all related to each other) - Sunlight is energy in the form of electromagnetic radiation
Most abundant form of energy comes from the Sun (Sun exchanged mass for
energy via nuclear fission)
First Law of Thermodynamics
- Energy can not be created or destroyed, only transformed
- Energy is always conserved
- The totally energy of a system is constant, but the form of energy can change
Energy associated with Volume change
- Heat energy of a gas is related to both volume and pressure
An Adiabatic Process is defined as when no heat is added or taken away from If you want to learn more check out What did socrates say about knowledge?

A "chain" of energy transformations
… In the end, all is heat
- The process of energy transformation tends to lead to heat
