As height is gained the outside air pressure on the balloon is reduced. This reduction allows the gas inside the balloon to expand.
The air molecules would expand, increasing the pressure of the balloon. When anything gets cold, it contracts, and when heated, it expands. Atoms and molecules are always moving - when something is hot, the molecules are moving faster and greater distances. When something is cold, the molecules are still moving, just slowly and at much smaller distances. You won't see much a difference while it's partially inflated, though there would be one. You can see results more drastically by heating a balloon that is near completely inflated. The more air molecules that are in the balloon, the greater the expansion. In other words, the bigger the balloon and more air that's in it, when heated you will see a larger change in the balloon size.
Helium goes into a balloon to make it float.
As the balloon rises, the air pressure outside the balloon decreases while the air pressure inside the balloon stays the same. This causes the balloon to expand because the higher pressure inside the balloon pushes against the lower pressure outside.
The inflated balloon has air inside it, causing it to expand and increase in size. The deflated balloon has no air inside it, so it appears shriveled or smaller in size.
A balloon inflates itself when air is blown into it through the opening. The pressure difference between the inside and outside of the balloon causes it to expand and take on its inflated shape.

the heat caused the air inside to expand.
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.
It is true that it will become larger as it risses in the atmosphere. This is because the pressure surrounding the balloon decreases, so the pressure inside the balloon wants to equalise with the outside pressure. This causes the balloon to expand as the inside air is trying to get out. That's why things get 'sucked out' of a plane if there if someone opens the door at 30,000 feet, the cabin pressure is trying to equalise by removing the objects and air inside it.
When you fill a balloon with air, the air molecules displace the surrounding space inside the balloon, causing the balloon to expand and stretch. The pressure of the air inside the balloon exceeds the pressure outside, creating tension in the balloon material, which keeps it inflated.
When you inflate a balloon, the air goes inside the balloon and fills it up. The air molecules push against the walls of the balloon, causing it to expand and take on its inflated shape.
The inflated balloon has air inside it, causing it to expand and increase in size. The deflated balloon has no air inside it, so it appears shriveled or smaller in size.
A balloon inflates itself when air is blown into it through the opening. The pressure difference between the inside and outside of the balloon causes it to expand and take on its inflated shape.
An inflated balloon may pop or explode on an extremely warm day due to the increase in temperature causing the air inside the balloon to expand rapidly. This increased pressure can exceed the balloon's capacity to contain the air, leading to a rupture.
When a balloon that was inflated in an ice bath is taken out into a warmer environment, the air inside the balloon will warm up and expand. This expansion increases the pressure inside the balloon, causing it to expand and possibly burst if the pressure becomes too high. This is because gases expand when heated and contract when cooled.
