Energy and Power (note + flashcard)

Zeroth Law

Helps define temperature

First law

Conservation of energy

Second law

Energy flows away from it’s source

Third law

As a system approaches absolute zero energy is not produced

Six major forms of energy

Thermal, radiant, electrical, mechanical, chemical, nuclear

Thermal

The vibration/movement of atoms within systems

Radiant

The electromagnetic energy that travels in transverse waves

Electrical

Energy made available by the flow of an electric charge through a conductor

Mechanical

Energy stored in the movement of objects or systems

Chemical

Energy stored in the bonds of atoms and molecules (biomass, petroleum, natural gas, and coal)

Nuclear

Energy stored in the nucleus of an atom -- the energy that hold the nucleus together

Sankey Diagram

Shows the type of energy that goes into a system and how the energy is converted, which also includes wasted energy, usually in the form of heat

Flow Diagram

Depicts how energy moves through a system and includes the type of energy and how that energy is generated and stored
