When a balloon floats towards you, it means that the air inside the balloon is less dense than the air surrounding it, causing it to rise and move in your direction.
The atmospheric pressure go on falling. So the pressure in the balloon. It takes lot of height to get the pressure reduced. I mean, the reduction in the pressure can not be easily measured for short height.
It floats in the air because of the helium inside. Helium's density is less than that of oxygen, same reason fat floats in water.
The ideal gas law helps to explain why a hot-air balloon floats in the air. As the air inside the balloon is heated, it expands and becomes less dense than the surrounding air. This creates a buoyant force that allows the balloon to float.
A balloon floats in the air when the molecules inside the balloon are less dense. The gas inside a helium balloon is in essence "lighter" than the air around it, causing a buoyancy effect which makes the balloon float. This can also be seen in hot air balloons when the air molecules are heated by the propane torch and excited, thus creating a less dense environment inside of the balloon compared to outside of the balloon.
An inflated balloon floats in water because the air inside the balloon is less dense than the water. The buoyant force acting on the balloon from the water is greater than the force of gravity acting on the balloon, causing it to float.
A balloon.
The atmospheric pressure go on falling. So the pressure in the balloon. It takes lot of height to get the pressure reduced. I mean, the reduction in the pressure can not be easily measured for short height.
As the balloon ascends into the atmosphere, the air pressure surrounding it decreases, causing the gas inside the balloon to expand. Eventually, the gas inside the balloon will expand so much that the balloon will burst or pop. Pieces of the balloon will then fall back down to the ground.
If you mean hot air balloon then it floats because hot air rises because it is less dense and with enough hot air caught in the balloon it can lift create enough lift to take off into the air. If you mean a helium balloon then it rises because helium in the balloon is less dense then the air around it. Since less dense things rise to the top the balloon will float.
It floats in the air because of the helium inside. Helium's density is less than that of oxygen, same reason fat floats in water.
A hot air balloon floats because the air inside the balloon is heated, making it less dense than the cooler air outside. This difference in density creates a lifting force called buoyancy, allowing the balloon to rise in the atmosphere.
Helium is lighter than air. hence helium balloon will float in air.
The ideal gas law helps to explain why a hot-air balloon floats in the air. As the air inside the balloon is heated, it expands and becomes less dense than the surrounding air. This creates a buoyant force that allows the balloon to float.
A hot air balloon floats in the air because it is buoyant due to the hot air inside the balloon being lighter than the cooler air outside. It is not propelled by engines or wings like an airplane, so it is more accurate to say it floats rather than flies.
The hot air is less dense than the air surrounding the balloon, so it floats in the surrounding air.
