it will produce static electricity and the static electricity will make the balloons stick together for about 2 seconds
the balloon becomes positively charged.
Static isn't it? or static electricity
No chemical reaction occurs when a balloon bursts
Before rubbing alcohol absorbs, it is a liquid. While it absorbs (heat), the phase change occurring is evaporation. As the alcohol takes in heat, it turns into a gas.
Yes
The minimum index of refraction for a glass or plastic prism to be used in binoculars so that total internal reflection occurs at 45 degrees is 1.414
Yes.
Rubbing a balloon on your head creates static electricity. This occurs due to the transfer of electrons between the balloon and your hair, causing the balloon to become negatively charged. The negatively charged balloon can then attract or repel other objects, creating small electrical sparks or causing your hair to stand on end.
Answering "What is a method of charge that occurs by direct contact?"Well there is always static electricity produced but rubbing certain objects together but i don't think you can convert that into a current. I believe it just dissipates
A balloon rises on the principle of buoyancy. This occurs when the net pressure on the bottom of the balloon exceeds the net pressure on top of the balloon.

It decreases. The colder air contracts, making the balloon shrink.
The balloon has a greater affinity for electrons so it obtains a negative charge after being rubbed against the sweater. The balloon, containing a highly negative charge, sticks to the wall because it is attracted to the positive charges in the wall (opposites attract). After a while, the balloon's extra electrons move to the wall and both objects become neutrally charged. Lacking any significant attraction, the balloon will fall off the wall.
Static generators, such as the Wimshurst and the Van deGraaff, both separatecharges by rubbing/scraping one surface against another. They differ in howthey store the charge before the zzapp occurs.
Elementary charge
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.
