Buoyancy is what helps hot air balloons float through the air.
In order for an object to float it must be surrounded by a denser atmosphere. Balloon pilots control the buoyancy of their balloon by heating the air inside the envelope of the balloon. When air is heated it expands (air molecules expand-becoming less dense) and it also rises when it is surrounded by colder denser air (molecules closer together becoming more dense). These changes in air density is what allow balloons to rise and fall.

A hot air balloon is held in the air by buoyancy, which is a force exerted by the difference in air pressure between the inside and outside of the balloon. The hot air inside the balloon is less dense than the surrounding cooler air, causing the balloon to float upwards.

Is a hot air balloon a balanced or unbalanced force?
A hot air balloon is balanced because the upward lift force from the hot air inside the balloon is equal and opposite to the downward force of gravity on the balloon and its contents. This balance allows the hot air balloon to float in the air.
What is the buoyant force of a hot air 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.
What force makes a hot air balloon rise up into the air?
Buoyancy is the force that makes a hot air balloon rise. By heating the air inside the balloon, it becomes less dense than the surrounding air and creates a buoyant force that lifts the balloon.
What happens when the force acting on a hot air balloon are balanced?
When the force acting on a hot air balloon is balanced, the balloon will remain at a constant altitude. This means that the buoyant force on the balloon is equal to the gravitational force acting on it. As a result, the balloon neither rises nor descends.
What are the two forces that affect a hot air balloon?
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.
Is a hot air balloon a balanced or unbalanced force?
A hot air balloon is balanced because the upward lift force from the hot air inside the balloon is equal and opposite to the downward force of gravity on the balloon and its contents. This balance allows the hot air balloon to float in the air.
What is the buoyant force of a hot air 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.
What does the hot air balloon have in the middle?
The hot air balloon has a basket in the middle, which holds passengers and the pilot. The basket is attached to the envelope of the balloon, where hot air is used to generate lift and make the balloon float.
What kind of balloons holds more air and why?
The kind of balloon that holds more air is a hot air balloon. This is because they are much larger than a standard balloon.
What force brings a hot air balloon to earth after the hot air is let out?
Erm.. no.. i believe its Buoyancy... this force causes u the hot air balloon to rise.. not Gravity..
What force makes a hot air balloon rise up into the air?
Buoyancy is the force that makes a hot air balloon rise. By heating the air inside the balloon, it becomes less dense than the surrounding air and creates a buoyant force that lifts the balloon.
What happens when the force acting on a hot air balloon are balanced?
When the force acting on a hot air balloon is balanced, the balloon will remain at a constant altitude. This means that the buoyant force on the balloon is equal to the gravitational force acting on it. As a result, the balloon neither rises nor descends.
A Hot-air balloon consists of a bag called the?
envelope, a burner, and a basket. The envelope is the fabric balloon that holds the hot air.
What are the two forces that affect a hot air balloon?
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.
How does hot air balloon work?
the balloon works with the poplo force forcing it up
What forces are used in a hot air balloon?
In a hot air balloon, buoyant force (lifting the balloon due to the density difference between the hot air inside the balloon and the cooler air outside) and wind force (pushing the balloon in a particular direction) are the primary forces involved in its movement. Additionally, the pilot can control the vertical movement using the burner to heat the air inside the balloon.
What force brings the balloon to earth after the hot air is let out?
Force of gravity
