(Special Junina Party)(Science)How the Balloon Flies?

Hi Guys!!!

In this post I talk about how balloons fly.

The air inside the balloon is hotter than outside. Thus, the mass of air not inside the balloon is smaller than the one occupied and is cold and therefore, by difference of density (relation between mass and volume), the balloon increases.

 That was all I had to say, then, bye ;-)
