When an icy impact occurred, the impactor's kinetic energy became heat energy, instantly melted some ice, gouged out a crater, and kicked up into Mars» thin atmosphere large amounts of debris mixed with water (liquid, ice crystals, and vapor)-- and complex organic molecules that obviously came recently from life.127 Then, the dirt and salt - water mixture settled back to the surface in vast layers of thin sheets — strata — especially around the crater.

«Only large groups of colliding molecules have a temperature — which is proportional to their mean kinetic energy.

Galerie Joseph Tang, a Right Bank newcomer in central Paris, is seeking to unlock some kinetic energy of its own with a solo show highlighting the large - scale installations of the young Latvian artist Daiga Grantina, whose potential in the United States, Mr. Proctor said, has yet to be realized.

Re 392 Chris Dudley — I don't understand what you mean by R ^ 2T ^ 4 — and there should be something about how optical depth is proportional to R, and also, if you're going a significant distance toward the center of such an object, there is the issue of spherical geometry; if the optical thickness is large enough across small changes in radius, then you don't need to account for the spherical geometry in the calculation of the flux per unit area as a function of the temperature profile and optical thickness; however, the flux per unit area outward will drop as an inverse square, except of course within the layers that are being heated through a different process (SW heating for a planet, radioactivity, latent and sensible heat loss associated with a cooling interior, gravitational potential energy conversion to enthalpy via compression (adiabatic warming) and settling of denser material under gravity (the later both leads to compression via increased pressure via increased gravity within the interior, and also is a source of kinetic energy which can be converted to heat)...

This kinetic energy has to be reduced during any transfer of energy, so a lot of wind turbines would theoretically reduce wind force by a large amount.

On a larger scale, M2E hopes to use kinetic energy to enhance wind, hydropower, and tidal power efficiency.

Within a volume of the atmosphere, none of the molecules are exactly at the mean kinetic energy, all are below or above average by at least a small amount, and some are above or below average by large amounts.

That case nonetheless remains relevant, because it illustrates by exaggeration something that remains true independently of how large the number of molecules gets: the mean molecular translational kinetic energy decreases with height, and it does so at a rate that is finite and non-zero, albeit negligible for most purposes.

But my understanding is that entropy discussions usually deal with macrostates rather than microstates, and it seems to me that the macrostate defined by a small volume and a given total molecular kinetic energy consists of fewer equally probable microstates than the macrostate defined by a larger volume and the same total molecular kinetic energy.

You might even argue that the molecular - translational - kinetic - energy difference is so small that Heisenberg's Uncertainty Principle dictates an extraordinarily large time uncertainty in its measurement.

I don't find this view satisfying, since it is in a microcanonical ensemble that the thought experiment in which mean kinetic energy is derived from temperature in accordance with PV = NkT is carried out — with, incidentally, no requirement that it be «large enough to apply said thermodynamics to.»

It's just that to me the most basic definition of temperature is indeed mean molecular translational kinetic energy; it avoids imprecise qualifications like «for ensembles large enough to apply said thermodynamics to.»

The fewer molecules must have sufficient gravitational energy that, if it were converted to kinetic energy, would be able to raise the temperature of a larger number of molecules in the lower layer the temperature in that lower layer.

of the added heat energy goes directly into the usual increased kinetic energy of the ideal gas, which is still precisely described by equipartition and still has a local MB distribution of velocities in any slice of the gas large compared to the MFP and small compared to, so that my detailed balance argument is not, actually asymptotically incorrect.

If we have a large number N of monatomic particles we say that the thermodynamic temperature is T, where the total kinetic energy is 3/2 NkT.

Joules Verne says: January 24, 2012 at 8:07 am...» The fewer molecules must have sufficient gravitational energy that, if it were converted to kinetic energy, would be able to raise the temperature of a larger number of molecules in the lower layer the temperature in that lower layer.

The kinetic temperature is the variable needed for subjects like heat transfer, because it is the translational kinetic energy which leads to energy transfer from a hot area (larger kinetic temperature, higher molecular speeds) to a cold area (lower molecular speeds) in direct collisional transfer.»

At larger heights there are fewer molecules... but the average per - molecule kinetic energy is unchanged.

It is stated that this reduced set has the same kinetic energy as the larger set — even though they all have higher potential energy.

The heat pipe analogy is more appropriate to the whole hydrological cycle, the essential energetics of which occur at the surface (the hot evaporating end), in the clouds where the larger water droplets accelerate condensation, and in precipitation, which converts very slowly acquired potential energy back into kinetic and thermal energy very quickly.
