1

Energy that is expended doing something

Work

2

A joule (J) is used to measure what

Energy and work

3

A type of mechanical energy which involves energy in motion

Kinetic energy

4

A type of mechanical energy which involves the energy of position

Potential energy

5

The kinetic energy of atom sized particles as they move in random directions

Thermal energy

6

Occurs when charged particles/electrons move between atoms causing atoms to form and break bonds with other atoms

Chemical energy

7

Occurs when the nucleus of an atom breaks apart or when particles are added to or removed from a nucleus

Nuclear energy

8

Says energy can be neither created nor destroyed but can only change from one form to another

The law of energy conservation

9

Always flows from higher temperatures to lower, never the other way

Thermal energy

10

Is the quantity of thermal energy transferred from one object to another

Heat

11

_Reactions give off energy

Exothermic

12

_Reactions absorb energy

Endothermic

13

What is the standard metric system (SI) unit of measurement for temperature

Kelvin

14

T=formula

T=t(c)+273.15* (in K)

15

t(c)=formula (in *C)

t(c)=T-273.15* (in *C)

16

t(f)=formula

t(f)=(1.8•t(c))+32

17

t(c)=formula

t(c)={t(f)-31}/1.8
