Did any change happen to the shape and the volume of a balloon when air was blown into it?
The balloons shape changed and went through an outward distortion. The volume of the balloon expanded as air was blown into it.
Will a balloon repel if you blow a stream of air between two balloons that are next to each other?
yes. tried it.
Is a balloon a solid?
Balloon is a solid because it has a definite shape when we blow or don't blow air into it.
If you blow a stream of air between two balloons that are next to each other the balloons?
They draw closer together. The high speed air causes a partial vacuum, the relative pressure on the outside of the balloons pushes them closer together. This is principle by which an aeroplane wing works. It is called the Bernoulli principle.
Why dont balloons float with human air like when you blow up a balloon it falls to the groud but when helium gets blown into a balloon it floats?
helium is lighter than air

Why will the balloons touched each other if you blow hardly in between them?
If you blow between them, you decrease the pressure of the air between the balloons. The air around them, which has greater pressure, will force them to approach each other.
Is a bursting balloon a physical change?
no, bursting of balloons is a physical change as the only change that occurs that that the shape of the balloon changes . Coming out of air is not a chemical change.
How do you cheat interlock?

Why does your heater not blow out warm air?
if the heater does not blow out warm air change the setting.
Why are hot air balloons circular?
Circles and spheres have the least amount of surface area per volume than any other shape, and so it is a very popular shape for hot-air balloons as less heat is dissipated through the skin of the balloon.That being said, hot-air balloons have been made in many different shapes.
