    there should be no math involved in this except logs ... yeah. Everything else is dimensions but I don't know if the number of atoms has dimensions

    m^3 * m/s^2 *m * kg/m^3 ----------------------------- = should be unit less joules/T *T

    (m^3 *(m/s^2)*m* ((kg )/m^3)) ------------------------------ j/T * T = 1 kg m^2/s^2 ---------------------- j 1 kg m/s^2 *m ---------------------- j 1 kg* acceleration *m ---------------------- j 1* newton* meter --------------- j newton*meter=j j/j=1
