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.
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.
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.
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.
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.
Helium goes into a balloon to make it float.

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.
When you stick a balloon to glass, it will not float on its own. The balloon will stick to the glass due to static electricity generated when rubbing the balloon against your hair or clothes. The balloon's ability to float is determined by the gas inside the balloon and the upward force it creates, not by sticking it to a surface.
A hot air balloon floats because the air inside is heated, making it less dense than the cooler air outside. This creates a buoyant force that lifts the balloon. If the air inside the balloon is not heated, it will not be less dense than the surrounding air, and the balloon will not float.
The gas inside of a balloon is less dense than the air outside of it if the balloon floats. If the balloon does not float the density of the gas inside of it is equal to or more dense than that around it.
The first hot air balloon, created by the Montgolfier brothers in 1783, worked by heating air inside a silk and paper envelope. When the air inside the balloon was heated, it became less dense than the surrounding air, causing the balloon to rise. This principle, known as hot air or thermal buoyancy, allowed the balloon to float in the sky.
Helium balloons float down due to the weight of the balloon being greater than the lift force generated by the helium inside. As the helium inside the balloon slowly leaks out over time, the lift force decreases, causing the balloon to float down.
