I asked this to QwQ and it started writing equations (newton's law) and arrived at T_2 < T_1, then said this is counterintuitive, started writing more equations and arrived to the same, starts writing an explanation on why this is indeed the case instead of what it is intuitive, and concludes to the right answer.

It is the only model I gave this and actually approached it by writing math. Usually I am not that impressed with reasoning models, but this was quite fun to watch.
