What is the process of warm air rising?
when you heat matter, it expands. When you cool matter, it shrinks. So if you have hot air in a larger body of cool air (lets say a hot air balloon in the sky) it will weight less than the surrounding body of cool air, since its less dense (because the air is hot, thus expanded). This creates buoyancy which lifts the hot air, and this case, the entire balloon.
Is the anchor more dense than a hot air balloon?
Yes, an anchor is more dense than a hot air balloon. Density equals the mass divided be the volume.For example:Let's say that they both take up the same amount of volume, the anchor has a higher mass than the hot air balloon so it has a higher density which is why the hot air balloon floats and the anchor will sink.yes it is.If a thing can float on water, it's density is lower than water, like a hot air ballon.If a thing can sink in water, it's density is higher than water, like an anchor.
What air force makes a air balloon go up and down?
This is the buoyancy force. Archimedes is credited with first formulating this into a mathematical principle: the buoyancy force of an object is equal to the weight of fluid it displaces. In the case of a hot air balloon, the "fluid" is the outside cool air and the balloon is displacing a volume of cool air equal to the volume of the inflated balloon. So you can say the buoyancy force F = V ρ g, where V is the volume of the inflated ballon, ρ is the outside air density, and g is gravity. A balloon can float because it is displacing this cool air with hot air which is less dense. The volume of hot air inside the balloon thus weighs less than the same volume of cold air outside the balloon. For a balloon to be float upwards, the buoyancy force has to be at least equal to the weight of the balloon (the balloon fabric, the gondola, the people, equipment and cargo, and the hot air inside). For example, for a balloon of 100,000 cubic foot volume (typical), with outside air at 20 deg C near sea level, the buoyancy force is about 7500 lbs. This force has to lift the gondola, people, equipment and of course the hot air inside the balloon, all of which have weight. By far the greatest percentage of that total weight is the heated air inside since there is so much of it.

Wherever the balloon is what can you say about the pressure of the air inside and outside the balloon?
Usually, the air pressure inside a balloon is very high because the plastic outer shell of a balloon wants to contract and press the air into a small space. High in the atmosphere, air pressure is much lower than on the ground. When the air pressure outside a balloon is bigger than the air pressure inside, the balloon switches from wanting to push in on the air to the air pushing on the balloon. as this happens to some parts of a balloon and not others, it is uneven and the balloon pops.Answer:There are two distinct cases:For child's rubber balloon the air inside is at higher pressure because it is being squeezed by the rubber that wants to return to its original size. Just like you have to apply pressure to a rubber band to keep it stretched.In the case of hot air balloons the pressure on the inside of the balloon is the same as the atmospheric pressure. The balloon in this case is like an upside down bucket of air that would like to rise. It fills the container but shares the pressure of its surroundings.
How high can a hot air balloon go?
I belive the record is 50,000 feet.The most enjoyable balloon rides are between 1200 feet and 3000 feet.(at least 1000 ft in city areas) some people also say that theGenerally, a hot air balloon flies at an altitude of 500 to 1500 feet.The world altitude record for a hot air balloon is 21,027 metres set by Vijaypat SINGHANIA (INDIA) on 26 Novemoffical height was 75,000it can go up for ever as long as you have enough fuel to keep it going but at a certain altitude,(like space) there is a lack of oxygen so the balloon will start to float around and the person(s) will die from lack of air
Would the air in an inflated balloon be potential energy?
i probably wouldn't say the air had potential energy just that an inflated balloon has potential energy.
