Sentences with phrase «same average kinetic energy»

If two bodies have the same average kinetic energy of their atoms, the will have the same temperature no matter how large [i.e. how much mass] the bodies are.

A mercury thermometer is going to register the same reading for a highly radiative gas like CO2 as it is for a barely radiative gas like N2 when they have the same average kinetic energy in the molecules.

Molecules of one mass don't have the same average kinetic energy as more massive or less massive molecules.

In equilibrium, molecules of one mass have the same average kinetic energy as molecules of a different mass.

If those two containers have the same temperature, they have the same average kinetic energy per particle (for a monatomic gas).

Over a sufficiently long period of time, it follows from the equipartition theorem and other principles of statistical mechanics that every molecule in a gas will have the same average kinetic energy, the same average potential energy, and the same total energy, as any other molecule.

Not exact matches

As implausible as it might seem at first, the average kinetic energy of the molecules that make it 17 km will be the same as the average KE of the molecules at the bottom.

On average, just as many molecules move up, with exactly the same velocity / kinetic energy profile, as move down, with zero energy transport, zero mass transport, and zero alteration of the MB profiles above and below, only when the two slices have the same temperature.

That's not necessarily the same kinetic energy as any individual molecule will have at any given time — it's the average that's the temperature.

What's stated is that eventually the average kinetic energy (the temperature) of all molecules will be the same throughout the gas.

He appears to think it's fine that molecules in the upper shell have more total energy, on average, than molecules in the lower shell so long as average kinetic energy is the same.

This is something that you have denied was possible on the ground that (allegedly) a gas can't have a lower density, the same average molecular kinetic energy, and yet the same temperature.

Within each region of the atmosphere that contains CO2, and within each region of the Earth surface, some molecules have above average kinetic energy and some have below average kinetic energy; the temps of the regions are proportional to the means of the kinetic energies in those regions, but the molecules are not all the same.
