wrong units[edit]

$U=V\varepsilon \sigma T^{4}$ I guess, there is a /c missing, since $[T^{4}\sigma ]=W/m^{2}$ Ra-raisch (talk) 22:21, 7 December 2016 (UTC)[reply]

I see, there is a constant a=4sig/c .... so is there still a factor 4 missing now? Yes, I found it in my own notes. Ra-raisch (talk) 22:45, 7 December 2016 (UTC)[reply]

$V^{1/6}/T$ [edit]

it must be V/T=constant since the equation ends to 1/6*dV/dT = V/T Ra-raisch (talk) 23:18, 7 December 2016 (UTC)[reply]

Combining these[edit]

how do you combine what? I don't ever get 2/3 but rather 4/3 or something entirely different. If you set dW_V = dW you loose dU and dQ, if you set dW_V=dU you get -4/3T^4dV=4VT³dT. Ra-raisch (talk) 11:03, 8 December 2016 (UTC)[reply]

Maybe setting -dW_V=dU leads to -2/3 T^4dV = 4VT³dT, that makes most sense of all varieties. Ra-raisch (talk) 11:48, 8 December 2016 (UTC)[reply]

V 1 / 6 / T {\displaystyle V^{1/6}/T} [edit]
