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
the heat makes the molecules inside the balloon travel faster, pushing outward on the balloon. This, the balloon expands when heated
Because as the balloon is heated, the gases on the inside of the balloon begin to expand and press out on the walls of balloon. If a balloon is refridgerated, the opposite is true: the gases on the inside of the balloon will begin to contract, causing the balloon to shrink.
It is reduced by haft
they pop

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.

The density decreases by half. You find the answer by knowing that density is equal to mass divided by the volume. If the mass stays constants and the volume is doubled, then the density is halved.

Air inside the balloon is heated. Hot air is less dense than the surrounding air, and thus the balloon rises.

If a balloon is inflated and tied closed, then held over a flame, it will surely pop. The heat of the flame will melt the rubber that makes the balloon.
