So this is the question I am working on as shown in the attachment.
I got stuck in the part that I highlighted, where they divided the Dynamic temperature by 1000.
WHY ?

Any help will be appreciated,

Thank you.

It's not that the dynamic temperature is divided by 1000. (Notice: there are units attached to the 1000). You have to convert 1 kJ (= 1000 kg-m^{2}/s^{2}) into its equivalent base units so that you can calculate the rise in temperature due to the velocity of the air.

It's given a gas of particles all identical which has T fixed and spin S. Let's ##g(\epsilon)## the density of orbital states and ##g(\epsilon) = g_0## for ##\forall \epsilon \in [\epsilon_0, \epsilon_1]##, zero otherwise. How to compute the number of accessible quantum states of one particle? This is my attempt, and I suspect that is not good. Let S=0 and then bosons in a system. Simply, if we have the density of orbitals we have to integrate ##g(\epsilon)## and we have...
