By rising when filled with lower density (hot) air than that surrounding it.
In conclusion, balloons float in the air due to the principle of buoyancy, which states that objects will float if they are less dense than the fluid they displace. The helium or hot air inside the balloon is less dense than the surrounding air, allowing the balloon to rise. Balloons demonstrate how manipulating density can be used to achieve buoyancy and enable objects to float.
The buoyant force acting on a balloon is equal to the weight of the air displaced by the balloon. The formula for buoyancy in balloons is: Buoyant force = Weight of air displaced = Volume of balloon * density of air * g, where g is the acceleration due to gravity.
Buoyancy force come from difference in density of the object and the surrounding. Buoyancy of the ship can change from the pay load inside its' space. More load per space reduce the buoyancy. For Balloon, buoyancy is change by increase temperature of gas inside to balloon since increase in temperature would cause gas to expand and had lesser density in its' cavity. In general, buoyancy increase or decrease by changing of density of the object or the surrounding medium.
In a hot air balloon, the burner heats the air inside the balloon, causing the air molecules to move faster and spread out, which decreases the density of the air inside the balloon. This lower density air is then buoyant compared to the denser air outside the balloon, causing the balloon to rise. This process exemplifies the particle theory by demonstrating how the behavior of air molecules can affect the overall density and buoyancy of the system.
The two forces that affect a hot air balloon are buoyancy and gravity. Buoyancy is the force that lifts the balloon due to the difference in densities between the hot air inside the balloon and the cooler air outside. Gravity acts to pull the balloon back down toward the ground.

In the process of inflating a balloon, air is pumped in to increase the density of the balloon. In scuba diving, a diver adjusts the air in their buoyancy control device to control their density and buoyancy in the water. Air is pumped into a hot air balloon to increase its density and provide lift for flight.

Hot gasses are less dense than cooler ones and therefore rise.A hot air balloon rises because the density of the hot air is less than the density of the cold air that it displaces. This causes buoyancy.
In a hot air balloon, the burner heats the air inside the balloon, causing the air molecules to move faster and spread out, which decreases the density of the air inside the balloon. This lower density air is then buoyant compared to the denser air outside the balloon, causing the balloon to rise.

Turning on the burner in a hot air balloon heats the air inside the balloon, reducing its density. This decrease in density causes the balloon to become lighter than the surrounding air, which helps it to rise. The heated air adds buoyancy, allowing the balloon to ascend.
Density of any balloon depends on the material of the balloon and how much the balloon is filled.
A balloon filled with light gas rises due to buoyancy generated by the difference in density between the gas inside the balloon and the surrounding air. However, as the balloon ascends, the air pressure decreases causing the gas inside the balloon to expand. Eventually, the gas will expand to the point where it equals the surrounding air density and the balloon will stop rising.
A balloon filled with argon will sink because argon is denser than air. The density of a gas affects its buoyancy in the surrounding air; denser gases will sink while lighter gases will rise.
Buoyancy lifts a balloon due to the difference in density between the air inside the balloon and the surrounding air. The balloon is filled with a gas that is less dense than the air, creating an upward force. This force, known as buoyant force, pushes the balloon upwards until it reaches a point where the forces are balanced and the balloon can float.
