 <p>Ken requests an episode on Fahrenheit, which really requires discussion of the two temperature systems, and how they are quantified.</p>
 <h3>Terminology</h3>
 <p>Centigrade: old fashioned term for Celsius<br /> Kelvin (K): less common measurement of temperature used for Science<br /> Thermal Equilibrium: en.wikipedia.org/wiki/Thermodynamic_equilibrium<br /> Zeroth Law of Thermodynamics: en.wikipedia.org/wiki/Zeroth_law_of_thermodynamics<br /> Absolute zero: en.wikipedia.org/wiki/Absolute_zero<br />
 </p>
 <p>My personal preference is Celsius. Less numbers to deal with in everyday use.<br /> Really Cold – Temperatures below 0°C<br /> Really Hot – Temperatures above 30°C<br /> The "American" thinking is temperatures go in 20's, 30's, 40's...etc. more work!<br /> Obligatory gun discussion<br /> Indirect conversation about PV = nRT formula<br /> Correction: the absence of pressure (vacuum) causes water to boil.<br /> Celsius and Fahrenheit are "measured" by the states of water boiling/freezing.<br />

Celsius
freezes at 0°
boils at 100°

Fahrenheit
freezes at 32
boils 212°

1 (K) Kelvin = -273.15°C
