Energy Basics
Question | Answer |
---|---|
energy is neither created nor destroyed, but can be converted from one form to another | First Law of Thermodynamics |
when energy changed from one form to another, some is always degraded into heat | Second Law of Thermodynamics |
enough energy to knock electrons from atoms forming ions; capable of causing cancer (ex: gamma-X-rays-UV light) | Ionizing Radiation |
stored energy, related to an object’s position (water behind a dam) | Potential Energy |
energy of motion, flowing water in a river, arrow in flight, electromagnetic energy, heat | Kinetic Energy |
Energy ____ through ecosystems | Flows |
from short wavelength, high energy to long wavelength, low energy = gamma rays, x rays, ultraviolet (UV) rays, visible light, infrared light, microwaves, radio waves | Electromagnetic spectrum |
