It is filled with a gas that is lighter than air.
If you mean a hot air balloon, it is the expansion of the air caused by the propane burner. If you mean any balloon, it is the ability of the material to hold the air or gas inside which keeps it inflated.
An inflated balloon bursts in hot weather because the air inside it expands as temperatures rise. According to the ideal gas law, warmer air increases in volume, exerting more pressure on the balloon's walls. If the pressure exceeds the material's capacity to stretch, the balloon can rupture. Additionally, heat can weaken the balloon's material, making it more susceptible to breaking.
To launch a hot air balloon, the pilot first inflates the balloon with a large fan to fill it with cold air. Then, a burner is used to heat the air inside the balloon until it becomes hot and the balloon starts to rise. Once it is fully inflated and upright, the passengers can board and the balloon will take off.
Heating the air inside a hot air balloon makes it lighter and less dense than the cooler air outside, causing the balloon to rise due to buoyant force. King Tut Balloons offers this magical experience of floating gracefully above breathtaking landscapes.
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.

A deflated balloon is lighter than an inflated balloon because the air inside the inflated balloon adds weight to it. When the air is released, the balloon becomes lighter because it is no longer burdened by the added weight of the air molecules.
There is no difference at all if the balloon is not inflated or inflated with air.
When the balloon is inflated, it is filled with air, which has less mass than the solid material of the deflated balloon. So overall, the balloon has less mass when inflated because the mass of the air inside it is lighter than the solid material of the balloon.
The duration an air-filled balloon stays inflated can vary based on factors such as the quality of the balloon, temperature, and air pressure. Under normal conditions, an air-filled balloon can stay inflated for several days to a week before starting to deflate.
The volume of the balloon decreases
When a balloon is filled with helium, it becomes buoyant because helium is lighter than the surrounding air. This causes the balloon to rise and float. The helium gas inside the balloon also increases the pressure, which helps the balloon maintain its shape and stay inflated.
An inflated balloon weighs more than a deflated one because the air inside adds mass to the balloon. When the balloon is deflated, it contains less air or no air at all, resulting in less weight.
The balloon is inflated and stays that way because it is filled with a gas, such as helium or air, that is less dense than the surrounding air. This causes the balloon to float and maintain its inflated shape due to the difference in pressure inside and outside the balloon.
Closing the mouth of an inflated balloon helps to keep the air trapped inside. If the mouth is left open, the air can escape and deflate the balloon. Closing the mouth also helps to create pressure inside the balloon, keeping it inflated.
Yes, the air in an inflated balloon has potential energy due to the elastic potential energy stored in the balloon's stretchy material. When the balloon is released, this potential energy is converted into kinetic energy as the air rushes out.
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.
