Thermal decomposition
A chemical reaction in a hot air balloon can be when the propane is heated up. That is a chemical reaction because something has heated up.
They expand due to the molecules speeding up.
Molecules will rapidly spread apart and move in every direction in the presence of a heated fluid, and tightly bunch up in cooler fluids.
The solvent is vaporized.
the heat makes the molecules inside the balloon travel faster, pushing outward on the balloon. This, the balloon expands when heated
the mass of the balloon increases because the size of the balloon has increased. :)
The gas will expand as it is heated.
it becomes low
Convection.

Convection.
new molecules starts to form
It decreases.
It is reduced by haft
when heated, molecules get farther away from eachother, causing the balloon to expand. once the balloon reaches its maximum capacity, further heating will cause the molecules to expand more than the balloon can contain and it will pop.
