Heating the air inside the balloon makes it less dense than the surrounding air, causing the balloon to float. As warm air is lighter than cool air, the balloon rises because of the difference in densities. This creates an upward force, known as buoyancy, that allows the balloon to float.
What else can I help you with?
Why does the heating in a hot air balloon allow it to float?
Heating the air inside the balloon makes it less dense than the surrounding air, causing the balloon to become buoyant and float upwards. This is due to the principle of buoyancy, where objects that are less dense than the fluid they displace will float in that fluid.
What must happen for a balloon to float in the air?
For a balloon to float in the air, it must be filled with a gas that is lighter than the surrounding air, such as helium or hot air. This creates a buoyant force that allows the balloon to rise and float.
How does heating the air inside a hot-air balloon make it to float?
Heating the air inside a hot-air balloon decreases its density, causing it to become lighter than the surrounding cooler air. This buoyant force generated by the temperature difference causes the balloon to float upwards.
Does a balloon float or sink on water and why?
A balloon filled with air will float on water because it is less dense than water. The buoyant force acting on the balloon allows it to float.
Explain in terms of density and Charles's law why heating the air allows a hot-air balloon to float?
Heating the air inside the balloon decreases its density due to Charles's law, which states that as temperature increases, volume increases assuming pressure is constant. The lighter, less dense air inside the balloon creates a buoyant force greater than its weight, allowing it to float in the denser, cooler air outside the balloon.

What is the name of the force that allows a balloon to float in air?
helium

In a hot air balloon air is heated by a flame Explain how this enables the balloon to float?
Heating the air inside the balloon makes it less dense than the surrounding air, causing the balloon to float upwards. As the air inside the balloon cools, it becomes denser and the balloon descends. The pilot can control the altitude by adjusting the temperature of the air inside the balloon.
How a hot air balloon operate?
A hot air balloon works by heating the air inside the balloon to make it less dense and more buoyant than the surrounding air. This allows the balloon to float upwards. By controlling the temperature of the air inside the balloon, the pilot can control the altitude of the balloon. Steering is done by moving the balloon up or down to catch the wind currents that will take it in the desired direction.
What happens to a hot air balloon that allows it to float through the air?
Air inside the balloon is heated. Hot air is less dense than the surrounding air, and thus the balloon rises.
Why will a hot air balloon rise and then float at a certain height in air?
increasing altitude decreases air pressure, this pressure gradient with gravity decides if things sink or float. heating the air in the balloon decreases the weight of the balloon and allows the downward pressure from above plus the weight of the balloon to be less than the upward air pressure from below. hence the balloon rises due to this force imbalance. the balloon reaches a constant height when all three are equal
How does heilum make a balloon float?
When helium is added to a balloon, it decreases the overall density of the balloon compared to the surrounding air. This causes the balloon to float because the buoyant force exerted by the helium is greater than the force of gravity acting on the balloon. This buoyant force allows the balloon to rise in the air.
Why do balloons float in the air?
Balloons float in the air because they are filled with a gas that is lighter than the surrounding air, such as helium or hot air. This creates a buoyant force that allows the balloon to rise and float.
