Yes, hot air balloons are less dense and therefore buoyant
============================================
Hot air balloons are buoyant to the extent that the weight of the hot air in the balloon is lighter than the free air. When the difference is more than the weight of the balloon and its contents it will be buoyant and will ascend.
A hot air balloon goes up because the air inside the balloon is heated, which makes it less dense than the surrounding cooler air. This creates a buoyant force that causes the balloon to rise. The pilot controls the altitude by adjusting the temperature of the air inside the balloon.
A balloon flies high because it is filled with a gas that is lighter than the air outside the balloon. This creates a buoyant force that causes the balloon to rise.
When the gas (air) in a hot air balloon is heated it becomes less dense. This makes the balloon more buoyant so it rises.Because heating the air inside the balloon makes it less dense than the air surrounding the outside of the balloon, so it will rise.
Increasing the air temperature inside the balloon will cause the air inside to become less dense and expand, making the balloon buoyant and rise. Conversely, decreasing the air temperature inside the balloon will cause the air to become denser and contract, making the balloon less buoyant and descend. By controlling the temperature inside the balloon, you can effectively control its altitude.
A hydrogen balloon rises due to the buoyant force that is exerted on it by the surrounding air. As it ascends, the air becomes less dense, causing the buoyant force to decrease until it eventually matches the weight of the balloon, resulting in it reaching a point of equilibrium and no longer rising.
A hot air balloon would not work on the moon.

it took about a year for the first hot air balloon to be made.

The buoyant force of air would be greatest for a hot air balloon because it relies on the principle of buoyancy to stay aloft. The heated air inside the balloon is less dense than the surrounding air, creating a greater buoyant force to lift the balloon. A bird and an airplane rely on aerodynamic lift generated by their wings to stay airborne, rather than buoyancy.
You would hear the intermittent sound of the gas jet used to reheat the air in 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 buoyant force exerted on the toy balloon by the surrounding air is equal to the weight of the air displaced by the balloon. This force is calculated using Archimedes' principle, which states that the buoyant force is equal to the weight of the fluid displaced by the object. The buoyant force is counter to the force of gravity and will keep the balloon floating in the air.
Under water they are as buoyant as each other but on land the balloon will float away and the Styrofoam will stay.
a small helium balloon :) i think.... i dont actually know the answer i just know that a small helium balloon will be very buoyant :)
