The "Demographic Transition" is a model that describes population change over time. It is based on an interpretation begun in 1929 by the American demographer Warren Thompson, of the observed changes, or transitions, in birth and death rates in industrialized societies over the past two hundred years or so.
By "model" we mean that it is an idealized, composite picture of population change in these countries. The model is a generalization that applies to these countries as a group and may not accurately describe all individual cases. Whether or not it applies to less developed societies today remains to be seen.

Answer: The balloon floats due to the difference in density
Explanation:
The air inside the balloon is warm as a result of it being heated. As warm air spreads out more, it has a lower density than cooler air.
A substance with a lower density rises over substances with higher densities as those sink lower. With the air in the balloon having a lower density, it will rise above the air outside which is colder and has a higher density.
