When a balloon rises high into the air it will expand and often will burst why?

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.

Why does a hot air balloon rises when air inside it is heated?
Heating causes the air inside the balloon to expand. Some of the warm air leaves through the bottom opening of the balloon, keeping the pressure constant.
Why can't a hot air balloon rise higher than it does?
Hot air balloons are limited in altitude because of adiabatic cooling. As you ascend in the atmosphere, the air becomes cooler. This alone would not be able to stop a balloon rising if there were enough fuel to continuously heat the air. However, as the balloon rises, the hot gas inside the balloon also rises. Logical right? When the gas rises, reduced pressure allows the gas to expand and as gases expand, the also cool. So, there will come a point, or pressure, where it become increasingly difficult to heat the air faster than it cools due to expansion and the balloon will stop rising.
How does air make a balloon fly?
air is heavier than balloon, air rises
What makes hot air balloon rise?
Hot air rises. As the air in the hot air balloon is made hotter than the surrounding air it rises.
How does the air change as a hot air balloon 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.
Why does a partially inflated weather balloon expand as it rises?
As height is gained the outside air pressure on the balloon is reduced. This reduction allows the gas inside the balloon to expand.
Why do balloons expand as they rise through the troposphere?
The ballon contains a fixed amount of gas producing internal pressure. At the surface, this pressure equals the surface atmospheric pressure. As the balloon rises, the atmospheric pressure drops, allowing the balloon to expand, keeping the internal pressure and external pressure equal. If the balloon is fully inflated at the surface it will burst at higher altitude.
Why does a partially inflated balloon expand as it rises?
The pressure in the balloon stays the same, but the pressure outside drops as the altitude increases. And as the outside pressure drops, the balloon expands.
What happens to the shape of a helium balloon as it rises?
As the balloon rises, the air pressure outside will decrease, and the balloon skin will deform till the pressure on both sides of the skin is the same. Thus your balloon will inflate in shape, towards the spherical, which is the limiting shape for a simple balloon.
What usually happen to a toy hellium filled balloon that rises high into the atmosphere?
It will usually burst. As it gets higher, outside air pressure is less, helium in balloon expands until balloon pops.
How would you make a balloon get the maximum elevation it can get?
Make the balloon capable of further expansion. That way as the balloon rises and the barometric pressure falls the balloon can expand and allow its internal gases to achieve a constantly decreasing density.
Why does a hot air balloon rises when air inside it is heated?
Heating causes the air inside the balloon to expand. Some of the warm air leaves through the bottom opening of the balloon, keeping the pressure constant.
Why are weather balloons partially infated before they're released into the atmosphere?
As you rise in elevation, the pressure around you decreases. This lower pressure would cause the balloon to expand, and burst if it was inflated to much originally. By starting it off only partly filled, it will expand to a normal size and not explode.
Why does the pressure outside the balloon decrease as it rises?
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.

Why balloon kept in sun burst after some time?
pressure x volume divided by temperature is a constant (Boyle's Law), or PV/T = constant. Since pressure does not change, as temperature increases so must the volume, so the balloon expands
Why a helium weather balloon expands as it rises in the air. assume that the temperature remain constant.?
When the helium balloon starts gaining height, the pressure decreases and as the gas molecules are very freely movable (higher than the normal). They move apart from each other in the mean while they make the balloon to expand. The decrease in atmospheric pressure relative to pressure inside the balloon causes it to expand.
