Problem P. 4027. (December 2007)

P. 4027. The volume of a balloon, filled loosely with Helium, increases if it is taken to a warm room from a cold street. Somebody stated that if we measure the increase of the upthrust exerted on the balloon, we can estimate the heat absorbed by the balloon. Is he right?
