Why is water attracted to Cup?

The water falling out of the top cup is made out of positive and negative pieces that are all jumbled together. But as the negatively charged cup approaches the stream, the positively charged parts of the water molecules (the hydrogen atoms) are attracted to the negative charge and move the whole stream toward the cup.

Why is a stream of water attracted to a charged rod?

Water is made up of polar molecules, each containing a negatively charged oxygen end and a positively charged hydrogen end. When a charged rod of material is brought near a thin stream of water, the water will be attracted to the charged rod and the stream of water will bend towards the rod.

Why is water attracted to a charged object?

A charged object attract small particles, such as dust. The charge in the object causes a complementary charge to develop in something close to it. The charge on the comb attracts the molecules of water in the stream. Because the molecules in the stream can be moved easily, the stream bends toward the comb.

What happens when you rub a plastic rod with a cloth?

When a plastic rod is rubbed with a cloth, the plastic rod becomes negatively charged as electrons from the cloth are deposited on the plastic rod.

What would happen if you charge a balloon by rubbing it against your hair and then brought it near another balloon that is neutral explain?

The balloon is charged by rubbing it on your hair. When you put it near a neutral object (paper, Styrofoam or puffed rice cereal), the electrons in the object repel away from the balloon and the protons are attracted to the balloon. The negatively charged balloon is then attracted and will “stick” to the object.

What did you observe when you placed the plastic object near the stream of running water?

Step-4: Observe what is happening when the plastic object is brought near to the flowing water. You will notice water bending towards the object that is rubbed against dry hair.

How does a plastic rod get charged by rubbing it?

When a polythene rod is rubbed with a duster, the friction causes electrons to gain energy. Electrons gain enough energy to leave the atom and ‘rub off’ onto the polythene rod. The polythene rod has gained electrons, giving it a negative charge. The duster has lost electrons, giving it a positive charge.

What is the charge of the plastic rod after rubbing?

When you rub the plastic rod (polyethylene terephthalate, glycol modified, or PETG) with the wool cloth, the rod charges negative. When you rub the glass rod with the silk, the rod charges positive.

How do you make water charge?

Put the wires in the water. Set the 9-volt battery next to the bowl then drop the ends of the wires into the bowl and leave them there. After a while, bubbles will begin to form. It will take some time for the water to bubble up, and the water will have a negative charge as long as the bubbles are present.

Why does my plate charge up when I rub it?

That’s because the foam attracts electrons from the cloth. Often, a plate fresh from the package will start with a positive charge. If it does, you will have to rub the plate long enough to cancel this initial charge before you can begin building a sizable negative charge.

What is the charge of a plastic rod?

Since the plastic rod is attracted to the glass one, the plastic rod must have the negative charge. Since then, we have learned that the ‘negative charge’ that he described is actually the result of an object acquiring additional electrons. Likewise, the ‘positive charge’ occurs as the result of the loss of electrons.

What are the two main ways of making plastics?

The two major processes used to produce plastics are called polymerisation and polycondensation, and they both require specific catalysts. In a polymerisation reactor, monomers like ethylene and propylene are linked together to form long polymers chains.
