Study Notes
Temperature Scales
Definition
- Temperature is a measure of the average kinetic energy of particles in a substance
- Heat is the transfer of energy from one body to another due to a temperature difference
Temperature Scales
-
Celsius (°C) Scale
- Developed by Anders Celsius in 1742
- Water freezes at 0°C and boils at 100°C
- Most commonly used scale in everyday applications
-
Fahrenheit (°F) Scale
- Developed by Gabriel Fahrenheit in 1724
- Water freezes at 32°F and boils at 212°F
- Used in some countries, especially in the United States
-
Kelvin (K) Scale
- Developed by William Thomson (Lord Kelvin) in 1848
- Absolute temperature scale, with 0 K as absolute zero (-273.15°C)
- Used in scientific and engineering applications
-
Rankine (°R) Scale
- Developed by William Rankine in 1859
- Absolute temperature scale, with 0°R as absolute zero (-459.67°F)
- Used in some engineering applications, especially in the United States
Conversion between Temperature Scales
- Celsius to Fahrenheit: °F = (°C × 9/5) + 32
- Fahrenheit to Celsius: °C = (°F - 32) × 5/9
- Celsius to Kelvin: K = °C + 273.15
- Kelvin to Celsius: °C = K - 273.15
