HPR - HPR1432: Fahrenheit 212

1 post in this topic

Please consider recording an episode for Hacker Public Radio. We are a you-contribute podcast. :) Ken requests an episode on Fahrenheit, which really requires discussion of the two temperature systems, and how they are quantified. Terminology Centigrade: old fashioned term for Celsius Kelvin (K): less common measurement of temperature used for Science Thermal Equilibrium: en.wikipedia.org/wiki/Thermodynamic_equilibrium‎ Zeroth Law of Thermodynamics: en.wikipedia.org/wiki/Zeroth_law_of_thermodynamics Absolute zero: en.wikipedia.org/wiki/Absolute_zero My personal preference is Celsius. Less numbers to deal with in everyday use. Really Cold – Temperatures below 0°C Really Hot – Temperatures above 30°C The "American" thinking is temperatures go in 20's, 30's, 40's...ect. more work! Obligatory gun discussion Indirect conversation about PV = nRT formula Correction: the absence of pressure (vacuum) causes water to boil. Celsius and Fahrenheit are "measured" by the states of water boiling/freezing. Celsius freezes at 0° boils at 100° Fahrenheit freezes at 32 boils 212° 1 (K) Kelvin = -273.15°C
