The "kT" is a rate constant, and is a function of temperature.

Ask someone from Hiroshima (15 kT) if they agree with that assessment.

Now in the production of particles we have that there are now (2 + N)kT, and if a lot of these particles, say n of them, are generated then E = NkT goes to E = (N + n)kT.

This time in a Euclidean setting is equivalent to a temperature with E = kT.

Well lets throw that into the Boltzmann distribution expE/kT and set E as ~1Mev for the energy difference between a proton and neutron.

This table shows the size, possible population, and mass (in kilotons or kT) of the external steel shell, the internal steel infrastructure, and the shield (total mass of steel shell plus rock).

The gas has been allowed to equilibrate at some well defined temperature, and as a result the average kinetic energy of each molecule is (3/2) kT (we ignore internal degrees of freedom and assume the gas is monatomic), where

One expression of what has now become known as “Landauer's principle” is that there are no possible physical implementations of the resetting operation that can do better that this, that is, reset a bit to zero converting less than kT ln 2 of work into heat.

Standard calculations show this requires at least kT ln 2 work.

N = 1, it is a standard calculation to show that the maximum work extracted as the partition moves to the side of the box is kT ln 2.
