When you rub an acetate rod with a damp wool, it causes the transfer of electrons from the wool to the acetate rod. This creates an imbalance of charge between the two materials, resulting in the acetate rod becoming negatively charged and the wool becoming positively charged. This process is known as triboelectric charging.
To make hot ice, you would need materials such as sodium acetate (often available as a powder or crystals), distilled water, a heat source, a glass container for mixing, and a stirring rod. Optional materials include a thermometer, a hot plate or microwave for heating the solution, and an ice bath for cooling and solidifying the hot ice.
Heating a copper rod does not change its mass. However, the density of the copper rod may change slightly due to thermal expansion, which can cause the dimensions of the rod to increase.
A normal solution contains 1 equivalent mass, in grams, of the solute in 1 litre of solution. Firstly, you calculate the mole mass of ammonium acetate. (77g). Weigh this out in a small, clean beaker. Add de-ionized water to dissolve the solid, then transfer the solution to a 1 litre volumetric flask, remembering to wash out the beaker three times with small volumes of de-ionized water, and add the washings to the volumetric flask. Similarly rinse the glass rod with small volumes of the water into the flask. Now add de-ionized water to the 1 litre mark and then mix the solution thoroughly by inverting the stoppered flask many times. Normality is not used much any more, molarity is more usual, though for this solid the two happen to be the same. Ammonium acetate has the systematic name ammonium ethanoate.
A metal rod is a long bar that is made out of steel or other metal materials. It can be used for construction.
Some of the electrons from the charged rod leap into the cork when they touch. When the charges on both items are equal they repel each other. This is because like charges repel while different charges attract.
When an acetate rod is rubbed with a duster, it acquires a negative charge. This is because the acetate rod has a higher affinity for electrons compared to the duster, leading to the transfer of electrons from the duster to the acetate rod.
When a metal rod is rubbed with wool, it gets energized because the metal rod and wool both have opposite effects.
the rod slightly attract each other
When a plastic rod is rubbed with wool, electrons are transferred from the wool to the plastic rod. This leaves the wool with a net positive charge due to the loss of electrons, while the plastic rod acquires a net negative charge due to gaining these electrons.
When a glass rod is rubbed with wool, electrons are transferred from the wool to the glass rod, making the rod negatively charged. This transfer of electrons causes the glass rod to become statically charged, meaning it has an excess of negative charge.
The iron rod becomes shinier and the wool cloth wears out. If you rub the same wool cloth on a hard rubber rod, the rod will become charged with static electricity and you will be able to pick up small bits of paper with it---whoopee!
When a rubber rod is rubbed with wool, electrons are transferred from the wool to the rubber rod. This results in the rubber rod becoming negatively charged and the wool becoming positively charged. This phenomenon is known as triboelectric charging, where rubbing two materials together causes the transfer of electrons between them.
When a rubber rod is rubbed with wool, electrons are transferred from the wool to the rubber rod, causing the rubber rod to become negatively charged. This transfer of electrons creates an imbalance of charge on the two materials, resulting in the rubber rod being negatively charged.
The acetate rod was negatively charged. This can be determined by bringing the rod near the electroscope. If the leaves of the electroscope repel each other, it indicates that the electroscope acquired a negative charge from the rod.
You build a charge when rubbing vinyl with a wool cloth. The wool cloth is very weak in holding electrons so when you rub it with the ebonite rod the electrons transfer onto the rod. The rod is negatively charged (assuming that the rod was neutrally charged). The wool becomes positively charged (assuming that the wool was neutrally charged)
Equal amount of positive charge in the woolReason: Just before rubbing both rod and wool are neutral. Now as we rub the rod with wool then loosely bound electrons get migrated right from wool to the rod. So rod gets excess electrons and balance between equal positive and negative goes off. So it gets negatively charged. If so then wool as it has lost electrons right from balancing it has to be positively charged
