the air is less dense at altitude, therefore it exerts less pressure. the gas in a sealed balloon will exert the same pressure regardless of it's altitude, so, with less outside pressure to overcome, the balloon will expand.
When you drop a balloon, gravity pulls it down towards the ground. As it falls, the air inside the balloon is pushed out through the opening, causing the balloon to deflate and eventually land on the ground.
A balloon drops to the ground because of gravity, which is a force pulling objects towards the Earth's center. The air inside the balloon is less dense than the surrounding air, causing it to be less buoyant and leading the balloon to fall due to gravity.
This is because there is always the same amount of air inside the balloon, providing the same amount of outwards force. Here on the ground, that outwards force is balanced by the air outside the balloon pushing on it. Higher in the atmosphere, however, there is less air, and therefore less force. Thus as the balloon ascends, there is a greater force pushing out than pushing in, and the balloon bursts.
A balloon can't blow itself up - it can only respond to internal and external forces. For example, if the pressure inside the balloon is greater than the pressure outside the balloon, it will inflate; if the pressure is greater than the balloon is able to stretch, it blows up. Balloons that are filled on the ground, for example, and then released into the sky may eventually blow up as they reach altitudes with lower air pressure.
A barrage balloon is a large helium-filled balloon that is tethered to the ground with steel cables. It is used as a defensive measure to deter low-flying aircraft from attacking ground targets. The cables are intended to damage or destroy the aircraft if they come into contact with them.
The question is not clear but i think it will be the same original size as it was initially.
As the balloon ascends into the atmosphere, the air pressure surrounding it decreases, causing the gas inside the balloon to expand. Eventually, the gas inside the balloon will expand so much that the balloon will burst or pop. Pieces of the balloon will then fall back down to the ground.
Maximum ground level concentrations occur a few hours after sunrise when inversion layers are broken up and brought to the ground.

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.
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.
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.
You climb out when the balloon lands on the ground and the basket is secure.
With helium filled balloons, they rise upwards as the gas inside is of a lower density than the atmosphere around them. The balloon will continue to rise and the gas inside it will expand as the atmospheric pressure decreases with increasing altitude. Eventually, the gas inside the balloon will expand enough to burst the balloon and the balloon will fall back to the ground. When and where this happens depends on weather conditions, air temperature, the rubber used in the balloon, etc.
