Feb 29 at 15:51 | comment | added | Him | For comparison, wikipedia gives one mol of $\mathbf{N}_2$ at 0 °C has about $5676$J of total kinetic energy due to temperature. The most [energetic particle ever observed](en.wikipedia.org/wiki/Oh-My-God_particle) hit the Earth's atmosphere with about $51$J of energy at $0.9999999999999999999999951$ times the speed of light. A .22cal bullet achieves in the ballpark of $200$J. | |
Feb 29 at 15:31 | comment | added | Him | You might get more precise answers if you use language about "the full distribution of velocities of air particles". Viz., the average kinetic energy of $1$ mol of $\mathbf{N}_2$ molecules could be $1$ unit because the kinetic energy of EACH molecule is $1$ unit, or because the kinetic energy of half of the molecules is $2$ units and the other half is $0$, or because the kinetic energy of $1$ molecule is $6.023 \times 10^{23}$ units and the rest are $0$. This last example is likely to cause tissue damage, but is unlikely to occur is "real-life scenarios". | |
