Yes, you can legally own a hot air balloon, but ownership comes with specific regulations and requirements. In many countries, including the United States, you must have the appropriate licenses and certifications to operate a hot air balloon. Additionally, the balloon must meet safety standards and undergo regular inspections. It's important to check local laws and regulations regarding ownership and operation.
No, a balloon floating in the air is not considered a projectile. A projectile is an object that is launched into the air and moves under the force of its own momentum and gravity, following a curved path. A balloon floating in the air is being supported by the buoyant force of the air around it.
A hot air balloon is powerless, relying on the winds for locomotion, while an airship has a motor, allowing it to drift with its own power.
A hot air balloon goes up due to the principle of buoyancy. When the air inside the balloon is heated, it becomes less dense than the surrounding cooler air, causing it to rise. As the balloon rises, it displaces an amount of air equal to its own weight, allowing it to ascend.
If there is warm air in the balloon, cooler air makes the balloon rise and if there is cold air in the balloon warmer air makes the balloon fall.
A hydrogen balloon in air will rise due to the fact that hydrogen gas is less dense than air. The balloon will continue to rise until it reaches an altitude where the density of the surrounding air matches its own density. If ignited, the hydrogen in the balloon can react with oxygen in the air and create a fire or explosion.
A person can legally own one, but I would assume that it would not be allowed into the air without special permission.
D: The hot air inside the balloon becomes less dense than the air outside the balloon.
The air inside a hot air balloon is the same as normal air around the balloon and the air you're breathing, only heated by the flame inside the balloon, hence HOT AIR balloon.
A balloon has a certain weight due to the material it's made of. When you blow air into the balloon, the weight of the air inside balances out the weight of the balloon material, making the total weight of the balloon and air the same as the original balloon.
To inflate a balloon, you can blow air into it by using your lungs to push air out of your mouth and into the balloon. Alternatively, you can use a pump to push air into the balloon.
The buoyant force on a hot air balloon is equal to the weight of the air displaced by the balloon. When the air inside the balloon is heated, it becomes less dense than the surrounding air, causing the balloon to rise. The buoyant force allows the balloon to float in the air.
The volume of a hot air balloon increases as the air inside the balloon expands when it is heated. As the balloon ascends and the air temperature decreases, the volume of the air inside the balloon decreases as well. The pilot can control the altitude of the balloon by controlling the temperature of the air inside.
