Temperature
Temperature- the measure of the kinetic energy of an object. The movement of the particles in a substance is directly related to the temperature. The hotter the object, the faster the molecules within in the object are moving. When the temperature decreases, the molecular motion slows down. Absolute zero is the temperature at which all molecular motion seizes completely.

**Temperature Scales**

Fahrenheit
- Primarily used in the United States. Water freezes at 32 degrees in this unit and boils at 212 degrees.

Celsius
- This unit of temperature is used by most other countries in the world. The point at which water freezes in this unit is 0 degrees, and water boils at 100 degrees.

Kelvin
- The Kelvin system is part of the SI temperature scale. This is the unit used by scientists to present experiments and papers. Zero on this scale is referred to as absolute zero, and is the point in which all molecular motion stops. Water freezes at 273.15 Kelvin and boils at 373.15 Kelvin.

Conversions:
These are used for converting between the different units around the world.

Fahrenheit to Celsius:

- Celsius = 5/9(Fahrenheit-32)

Celsius to Fahrenheit:
- Fahrenheit = 9/5(Celsius)+32

Celsius to Kelvin:
- Kelvin = Celsius + 273.15

Kelvin to Celsius:
- Celsius = Kelvin-273.15

Kelvin to Fahrenheit

- Fahrenheit = (Kelvin-273.15) 9/5(Celsius)+32

Fahrenheit to Kelvin

- Kelvin = 5/9 (Fahrenheit- 32) + 273.15
