Materials: *inflated balloon hair *hair dryer *water *spray bottle Procedure: 1. ) Dry your hair with a hair dryer to be sure it is good and dry. 2,) Step out into the cold weather to get hair cold.
3. ) Rub the balloon on your hair to create a static charge. 4,) This causes your hair to stand out on end. S. ) In order to decrease the static charge put some water drops on the balloon.
6. ) Again rub it on your hair. 7. ) The strands of hair that got wet no longer had static charge. 8.
) Now spray your entire head of hair with water. . ) Then rub the balloon on your hair. 0. ) You will no longer have static charge in your hair.
Results (Data): I. The charging Of the balloon is local; the charge doesn’t spread all over the balloon if it is just rubbed in one place. The balloon is an insulator. 2. The balloon Will stick to all types Of walls as well. The reason for this is that the neutral object is popularizing. When the charged object gets near the uncharged one, it attracts all Of the opposite charges closer to the charged Object.When bono materials are rubbed together (like a balloon and your hair), one will SSE electrons and one will accumulate them.
Producing Static Electricity Sometimes the outer layer of the object has negatively-charged electrons and the atoms are rubbed off, producing atoms that have a positive charge. The balloon that did the rubbing will accumulate a negative charge as it gets extra electrons. During dry weather, these excess charges do not disapprover easily, and you get static electricity. During humid weather, the electrons flow through the damp air and the object become electrically neutral.Conclusions: have learned hat dry weather does create a static charge. But I’m not convinced the cold has anything to do with it.
I do believe there is more humidity in the air on warm or hot days and this may be Why they State that cold dry weather creates static charge. Think on a hot very dry day with no humidity we would see the same results. It seems the water or humidity in the air is what keeps the static charge low. I know this because when I added the water from the spray bottle to my hair the static charge was reduced and eventually eliminated.
