Everything
A water balloon is filled with water, and other balloons are filled with air or helium.
One difference is that a hot-air balloon is uncontrollable and can't be maneuvered in different directions while a plane can move in various directions.
No.
Just the density difference between the balloon and surrounding atmosphere is so great that the balloon is able to lift itself and people.
There is no difference at all if the balloon is not inflated or inflated with air.
A ballast is heavy weights or sand bags to stabilize a ship or air balloon while an anchor is weight that holds the ship or air balloon to float away
A hot air balloon does not have any mean of steering and does not have permanent flotation. An airship has a permanent means of flotation (lighter than air gas bags) and a means of propulsion.
yes, because in this case meta center lies below the center of pressure is above. ballon moves due to difference of pressure
Yes
a hot air ballon uses the hot air to rise as the hotter air has lower density while a gas ballon contains a light gas such a s helium and is not released while in flight only added
A full balloon contains more gas than an empty balloon (even an empty balloon contains a little air). Therefore a full balloon is heavier than an empty balloon (assuming the balloons are the same weight to begin with). However, if filled with a lighter-than-air gas, such as helium, the full balloon will defy gravity due to its increased buoyancy. The only other difference is that the skin of a full balloon will be stretched and will therefore be much thinner than the skin of an empty balloon. This stretching increases the pressure upon the gas contained therein, therefore the gas is compressed inside the balloon.
A helium balloon does not need energy to rise in the air. A hot air balloon needs fuel to rise in air. That is it needs heat energy to rise in air.i love Pizza squares i hope they put helium in then one dayHelium relies on the fact that helium is lighter than air. Hot air balloons rely on the fact that hot air has less volume than cold air and is lighter than the air around it. hot air balloons use hot air to cause the balloon to lift as helium balloons use a special gas to cause lift
