Comparison of Temperature Scales[Source: Wikipedia]
|Kelvin (K)||Celsius (°C)||Fahrenheit (°F)|
|Lowest recorded natural temperature on Earth|
(Vostok, Antarctica - July 21, 1983)
|Water freezes (at standard pressure)||273.15||0||32|
|Average surface temperature on Earth||288||15||59|
|Average human body temperature||309.95||36.8||98.24|
|Highest recorded surface temperature on Earth|
(Al 'Aziziyah, Libya - September 13, 1922)
|Water boils (at standard pressure)||373.1339||99.9839||211.97102|
|The surface of the Sun||5800||5526||9980|

Heat and Temperature
Eureka! - Temperature vs. heat
Learn the difference between "degree of hotness" and "quantity of hotness".
Eureka! - Measuring temperature
You need something better than just "too cold" or "too hot", don't you? Learn how Anders Celsius came up with the solution…
Eureka! - Heat as energy
Learn that heat is just another kind of energy, and can be transmitted.
Can an individual atom be hot or cold? Can it even have a temperature? Find out now!
The Transmission of Heat
Eureka! - Conduction
Learn that heat can be transmitted by the vibration of an atom (or molecules) to its neighbours… which is what makes metals be so good heat conductors.
Eureka! - Convection
Learn that heat can also be conveyed by fluids thanks to the principle of buoyancy.
Eureka! - Radiation
And lastly, heat can also travel in the form of waves.
