How do you deflate a balloon by using a lighter?
The heat from the lighter, when placed on the surface of the stretched surface of the balloon,would melt the plastic of the balloon and allow the air inside the balloon to escape, so deflating the balloon.
What creates pressure?
Pressure inside of a balloon is created by the movement of the air molecules against the inner surface of the balloon. The more air inside the balloon, the more molecules that are hitting the same surface are, so there is more pressure.
Why doesn't a balloon pop with a needle through it?
A balloon bursts when the surface tension of the balloon's rubber is broken. If tape is put on the balloon and a needle inserted, the surface tension is held together by the tape.
Does the radius increase if a charged rod is brought closer to a gas filled balloon?
If a charged rod is brought close to a gas filled balloon, one will notice a change in shape in the balloon. In short, the charge of the rod works on the molecules of the gas within the balloon and cause the balloon to elongate.Ê
Does a silk cloth rubbed on a balloon cause positive or negative charge?
Negative. Rubbing fabric onto a balloon causes an electron buildup on the balloon surface because its material has high insulative properties.
An inflated balloon sufficiently weighted with a brick floats just at the surface of a lake if the balloon is brought down 1 meter below the surface and then let go will it go back to the surface?
yes

How can you put a needle in a balloon without popping it?
at the part where you blow it up Take a piece of tape and place it over the outside of the balloon. Poke the needle through the tape and through the surface of the balloon. The balloon will not pop because the surface of the balloon cannot expand, thus popping the balloon.

What would happen to a balloon full of air if you moved it from above a water surface to ten feet below the water surface?
The volume of the balloon would decrease. The pressure of the water would press inward on the balloon and cause it to shrink in volume.
What is in the pond?
standing surface water
What makes a balloon pop when hit with a sharp object?
Well when a balloon gets struck with a sharp object, it puts a hole in it and the surface tension is broken. The surface tension on a balloon is maxed out on the sides where the material is thin.When you poke it there is no room for it too expand.

Is a swamp moving surface water?
No it’s standing surface water
Where would you be standing if you where standing on the northernmost point on the earths surface?
the north pole
Do a balloon keep it's shape because air particles inside it push against the inside surface of the balloon?
Yes.
How is nitrogen in the atrmosphere brought to the earth's surface?
nitrogen is brought to earths surface by the gravitational pull of zero gravity
