-- Inflate the balloon with some substance that is less dense than air. OR -- Inflate the balloon with air, then heat it after it is sealed.

Heating causes the air inside the balloon to expand. Some of the warm air leaves through the bottom opening of the balloon, keeping the pressure constant.

Either by releasing some of the air it contains or by not applying more heat - as the air cools the balloon descends.
Pros : travel easy, got to places faster Cons : air pollution, gas prices
There really are not any cons to having a quiet air compressor. The pros are many. There's nothing like a quiet running machine without all the clicks and clanks.
pros: higher security for the country, ads more pride for the country... cons: may be used in negative ways,cost lots of money and of course pollutes the air
Pros would be electric power is cheaper better for the environment better for the air we breath in. Cons it's hard to find a gas station that can charge its battery so you have to charge it at home and that could be a hasle

Some Pros to screening at air ports would include: >Catching drug smuglers >Stopping an injustice before it happens Although some would see it as racist to point out a cetain race as the blame for most of the trouble that happens Some Cons would include: >Be accused of being a racist >Pinning the wrong person for a crime because of their race
The pros of barefoot shoes are better grips on the ground and being able to run more efficiently. The cons are sore calves, shoes get smelly faster because the separated toes make it harder to air out and fractured foot bones.
pros: - Cheap - efficient - easy for on the go use - sanitary product for one time use Cons: - no biodegradable - Healthy Risks - nervous system - takes over 1 million years to decompose - causes pollution to the air, when burned
The answer is fairly simple, while some believe that a balloon bursts when near hot air because the balloon simple melts, it actually has to do with the pressure inside the balloon. When near hot air, the air inside the balloon expands slightly, causing a change in pressure, and causing the balloon to burst.
If a hot air balloon, then stop heating the air. If a lighter-than-air balloon then release some of the gas.
For a balloon that is sealed and not full the volume of air inside the balloon will increase as it is heated. This is not however how hot air balloons work. A hot air balloon is essentially a fixed volume when it is inflated. If the air inside the balloon is heated the air inside becomes less dense so some of the air exits the balloon via the mouth of the balloon. As the air inside the balloon cools it becomes more dense so some air is ingested via the mouth of the balloon to keep it full. With each heating and cooling cycle, the pressure inside the balloon remains constant, the volume of the balloon remains constant but there is this movement of air out of and back into the balloon.

Airplanes Pros and Cons=PORS==- Fastest way to transport people and cargo==- Safest way to travel==-Can bring food and medicine to remote areas==-You don't have to drive==CONS==-The high altitude causes airsickness in some people==-They burn a huge amount of fuel in the air which causes pollution==-People who live near the airports air pollution is a problem==-When not treated properly it can become dangerous==-Effects the o zone layer and causes global warming=
