It can range from the stratosphere to the mesosphere, then they will be consumed by pressure and pop
It rises until the air it displaces weighs no more than the balloon and everything hanging from it weighs.
It will usually burst. As it gets higher, outside air pressure is less, helium in balloon expands until balloon pops.
The pilot blacks out and dies, then comes back as a zombie
The pressure outside the balloon doesn't change when the balloon rises. By a balloon rising, I assume that air is being placed into the balloon. As the balloon fills with air, the pressure inside the balloon will increase. Since the balloon can stretch, the increasing pressure against its inner walls will cause it to rise, or more correctly put, expand. Eventually, the balloon will be stretched to its fullest capacity if more air is placed inside it. When it pops, the bang you hear is the high pressure of the atmosphere inside the balloon equalizing with the lower pressure of the atmosphere outside the balloon.
air is heavier than balloon, air rises
Bread Tide Temperature Balloon Balloon Flag Smoke Prices Heat rises.
A combination of heat from the sun and the lower pressure of the surrounding air the higher you go, causes the gas in the balloon to expand. Along with the sunlight weakening the balloon material, it will burst.
The volume of the balloon will increase as it rises in the air. This is because the atmospheric pressure decreases at higher altitudes.
air is heavier than balloon, air rises
Hot air rises. As the air in the hot air balloon is made hotter than the surrounding air it rises.
As the air in the balloon is heated from the flames, the air becomes lighter. So much lighter than the surrounding air that the balloon eventually rises from the light air in it.
the balloonist would turn off the burner, allowing the air inside the balloon to cool down. Hot air rises so as the air cools down the balloon will lose altitude.
