Helium is not only very light, it is also monatomic, it's particles are all made up of a single atom. Air molecules, oxygen, and nitrogen mainly are larger and hevier and diffuse through much more slowly.
Scientists describe winds as the movement of air in Earth's atmosphere caused by differences in air pressure. These pressure differences result from variations in temperature, geography, and the Earth's rotation. Scientists use mathematical models and observations from weather stations, satellites, and weather balloons to study and explain the behavior of winds.
It's due to static electricity build up. The balloons have become charged with electricity and it is the same charge on both balloons (either positive or negative). Opposite charges attract, identical charges repel each other.

It helps explain metallic bonds.
The abstract noun forms for the verb 'to explain' are explanation and the gerund, explaining.
"Lighter than air." Think about it for a second.
Not much. While it's true that meteorologists do use balloons to send up weather probes, they tend to use gas balloons instead. It's simpler, cheaper and works better in their conditions.
Like (same) charges repel.
When air is blown between two balloons, the air flow from the blower creates a low-pressure area between the balloons. This low pressure effectively pulls the balloons towards each other. The Bernoulli principle, which states that moving air has lower pressure, helps explain this phenomenon.
The hot air balloons air pressure is usually used to explain the principle of buoyancy.
Convection explains the ability to fly hot air balloons because hot air rises due to its lower density compared to cooler air. As the air inside the balloon heats up, it becomes less dense and creates buoyancy, lifting the balloon. This convection process allows the balloon to float in the cooler air above.

There a several things that could explain some UFOs. Secret military aircraft, anomalies in the atmosphere, weather balloons or somebody pulling a hoax. Most sightings have logical explainations. But there is a small percentage that can't be explained. This small percentage is what becomes a UFO.
Archimedes' principle can be applied to gases through the concept of buoyancy. In a fluid, a gas bubble will experience an upward buoyant force equal to the weight of the fluid displaced by the bubble. This principle helps explain why gases rise in a fluid or why hot air balloons float in the atmosphere.
Inflating large bags or balloons inside a sunken ship's hull creates buoyant force that helps lift the vessel towards the surface. As the bags fill with air, they displace water, reducing the overall weight of the ship and allowing it to rise. This method is effective because it takes advantage of the principles of buoyancy to counteract the gravitational force pulling the ship downward.
Dalton's Law states that in a mixture of gases, the total pressure is the sum of the partial pressures of each gas. While it doesn't directly explain how hot air balloons rise, the principle of buoyancy is central to their operation. When air inside the balloon is heated, it expands and becomes less dense than the cooler air outside, causing the balloon to rise. This buoyant force is a result of the difference in density rather than a direct application of Dalton's Law.
