1.7 mK, temperature record for helium-3/helium-4 dilution refrigeration, and the lowest temperature which may be sustained for arbitrarily long time with known techniques. 2.5 mK, Fermi melting point of helium-3; 60 mK adiabatic demagnetization of paramagnetic molecules; 300 mK in evaporative cooling of helium-3
(Note - the relation between pressure, volume, temperature, and particle number which is commonly called "the equation of state" is just one of many possible equations of state.) If we know all k+2 of the above equations of state, we may reconstitute the fundamental equation and recover all thermodynamic properties of the system.
When stated in terms of temperature differences, Newton's law (with several further simplifying assumptions, such as a low Biot number and a temperature-independent heat capacity) results in a simple differential equation expressing temperature-difference as a function of time. The solution to that equation describes an exponential decrease of ...

In other words, the two numbers are within about a factor of 10 of each other. [1] For example, 1 and 1.02 are within an order of magnitude. So are 1 and 2, 1 and 9, or 1 and 0.2. However, 1 and 15 are not within an order of magnitude, since their ratio is 15/1 = 15 > 10. The reciprocal ratio, 1/15, is less than 0.1, so the same result is obtained.

For strongly temperature-dependent α, this approximation is only useful for small temperature differences ΔT. Temperature coefficients are specified for various applications, including electric and magnetic properties of materials as well as reactivity. The temperature coefficient of most of the reactions lies between 2 and 3.
A third interception from Daily in the fourth quarter sealed things for Navy. Army ranks second in the country in rushing yards per game, picking up an average of 314.4 yards each game.
