Study Notes
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).
