Explain how the total amount of energy in the universe remains constant

First law of thermodynamics
Law of conservation of energy

Energy can neither be created nor destroyed it can only change form

1

Define energy

Ability to work or cause change

If objects do work they use energy

Energy = joules

2

What are the six forms of energy

Thermal electrical, chemical radiant nuclear mechanical

3

What is thermal energy

Random motion of particles friction changing temp

4

Electrical energy

Electric charge of motion magnets and electric circuits converted

5

Chemical energy

Stored in bonds Bond Adams together bond broke energy release

Food and fuel

6

Radiant

Charge particles Excelerator each color of light represents different amount of energy

7

Nuclear energy

Nuclei of Adams source movement of nuclear particle

Sun -> radiant

8

Mechanical energy

Objects movement position or both

9

Describe entropy

Nature's tendency towards disorder

10

Relate energy transfer to entropy

More transfers more entropy less usefulness

11

Relate entropy to usefulness in a closed system

Entropy increases usefulness decreases
