Temperature Scales

Temperature is a comparative measurement of hot or cold.
A body that feels hot usually has a higher temperature than a similar body that feels cold.
Temperature is a measure of the average kinetic energy of the atoms/molecules in a substance.
As temperature rises, the average kinetic energy of the molecules increases, and the average speed of the molecules in the substance increases.
As temperature decreases, the average kinetic energy of the molecules decreases, and the average speed of the molecules in the substance decreases.
Common units for measuring temperature are Celsius (°C), Fahrenheit (°F), and Kelvin (K).

Celsius Scale

Invented in 1742 by Anders Celsius.
Divides the range of temperature between the freezing and boiling points of water into 100 equal parts.
Temperatures on the Celsius scale are known as degrees Celsius (°C).

Fahrenheit Scale

Established by Gabriel Daniel Fahrenheit in 1724.
Many countries now use the Celsius scale.
The United States uses Fahrenheit. The Fahrenheit scale divides the difference between the melting and boiling points of water into 180 equal intervals.
Temperatures on the Fahrenheit scale are known as degrees Fahrenheit (°F).

Kelvin Scale

Named after William Thompson Kelvin.
A British physicist who developed it in 1848.
Extends the Celsius scale to absolute zero.
Absolute zero is a hypothetical temperature characterized by a complete absence of heat energy.
Temperatures on the Kelvin scale are called Kelvins (K).
