[eli5] Why temperature is not relative if velocity is relative

352 views

So, we all know whether a train is moving depends on where the observer is. For passengers riding on it, the train is not moving. And high temperature are just particle moving with high speed. Is it possible that some observers will find a hot object cold? Just like the passengers on the train Thanks in advance!

Temperature is a scalar value measuring the average thermal energy of a substance. Velocity is a vector value measuring the change in displacement. To measure the change in something you need a starting point.
