static and lightning
Lightning is a discharge of static electricity in the atmosphere, which causes a bright flash of light. When lighting goes through the air, it heats the air to degrees hotter than the sun's surface about 50,000 degrees fahrenheit. This heating causes the air to expand and contract. This causes the sound called thunder. Lightning is caused by a build up of negative ions in the atmosphere which discharges into the ground causing the negative ions to go with the positive ions in the ground.Static electricity is negatively and positively charged atoms. A static charge on the other hand is a individual atom with a negative or positive charge. There are three types of charges negative positive and neutral. Negative and positive ions attract. But two negatives repel each other, just like two positives will. Neutrally charged ions can attract to both negative and positive ions, because they have and balanced charge of negative and positive ions, this means it has the same amount of negative and positive ions. This is where the following rule is true "opposites attract, and likes repel." Static electricity is generated when two different objects are rubbed together and some electrons are stolen from one object and then start to collect o
website: http://tqjunior.thinkquest.org/6064/history.html Some techniques were developed to help prevent static problems with the production of static , the two major techniques are chemicals, or the use of carbon and or metal fillers. With the chemical way of controlling static the chemicals are mixed with the molding palettes or powder. The second way is to apply the chemicals directly to the surface of the plastic that has the molding. These two chemical methods work, because they help distribute the static into the air, by increasing the conductivity of the plastic. With the metal/carbon filler method you mix in the metal or carbon pellets in with the molding pellets/dust. This way works because it helps bring up the conductivity of the plastic molded with the fillers. Although these techniques for getting of the static may sound good, there are drawbacks, like with all good things. The chemical method corrodes the machinery and lets bacteria and/or fungus to grow in the product or production equipment it also easily wear out. The metal/carbon filler has its own set of problems, They either work themselves out of the product, because the fillers don't mix well with the plastic, and cause the work areas to get dirty (can be a major problem in some areas). The fillers also make plastic opaque, so that will make it difficult to track while being produced. This is bad because the product would need to be tracked to see how efficient the work is going. Static Prevention in Plastic Production, 3 Now because opposites attract and like repel the reason hair stands up when you rub something on it can be explained. When something is rubbed in a dry place, the thing takes electrons from your hair, leaving your hair with a positive charge it stands up as far away as possible from the other positively charged hairs. There reason there is little static electricity in areas with a high humidity, like the Virgin Islands, is because the humidity in the air is a conductor of electricity, so it helps trancfer the free electrons to an area that can accept electrons, like the earth so not many free electrons stay on any object that is saturated.
