It is reduced by haft
The kinetic energy of the particles inside the balloon increase. This then expands the volume of the balloon.
It expands until the temperature is high enough to compromise the balloon's skin.
because the density in the balloon is heated so it rises higher than it being unheated
The air becomes less dense as it expands making the balloon appear to self inflate.
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.
Heated gas has a lower density than environmental air.
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.

the heated air inside of the balloon has less density than the cold outside air so the hot air is more buoyant (e.g. the bowling ball sinks but the beach ball floats because the density of the beach ball is less than the water)
