Why it is easy to charge polythene by rubbing but not copper?
When you rub plastic, you transfer electrons from one material to the other. ... Because plastic is an insulator, the electrons cannot flow through it so they effectively get stuck there they are static
Why is it easier to charge polythene by rubbing but not copper?
Polythene has a higher tendency to gain electrons from other materials due to its structure, making it easier to become negatively charged when rubbed. Copper, on the other hand, has a more stable electron configuration and lower affinity for gaining or losing electrons, making it harder to charge through rubbing.
What makes matchstick burn with matchbox?
A matchstick is coated with a mixture of phosphorus and an oxidizing agent on its tip. When struck against the matchbox, friction generates enough heat to ignite the phosphorus, which then reacts with the oxidizer to produce a flame.
What is the charge on a piece of rubbed amber?
Friction strips electrons so the rubbed amber would take on a negative charge. Actually, friction causes charges to shift. Charges are indeed stripped from something, but they are collected up by something else. Amber does, indeed, become negatively charged by rubbing it with, say, fur. The phenomon is called triboelectric effect. And a link is provided.
What type of charge does plastic collect when rubbed?
Plastic typically becomes negatively charged when rubbed, meaning it gains excess electrons. This can cause the plastic to attract positively charged objects or repel other negatively charged objects.
What charge does a polythene rod acquire when rubbed with a duster?
A polythene rod acquires a negative charge when rubbed with a duster. This is because electrons are transferred from the duster to the polythene rod, leaving the rod with an excess of electrons and a negative charge.
Why does polythene have a negative charge with a cloth?
When polythene is rubbed with a cloth, electrons are transferred from the cloth to the polythene, causing the polythene to become negatively charged. This transfer of electrons creates an imbalance of charges between the two materials, resulting in the polythene having a negative charge.
What will happen if a polythene rod rubbed with duster brought near another polythene rod also rubbed with a duster?
The two polythene rods will repel each other. This is because when the rods are rubbed, they acquire a net positive charge which causes them to repel each other since like charges repel.
When metal rod is rubbed against polythene bag or sweater it attracts or not?
When a metal rod is rubbed against a polythene bag or sweater, the rod becomes charged with static electricity. The metal rod may be attracted to the polythene bag or sweater due to the opposite charges present on each material.
How to charge an object by friction?
An object can be charged by friction when rubbed against another surface such asa) polythene rod rubbed against a woollen cloth.This occurred because the woollen cloth lost some of it negative charges when it was rubbed, the negative charges was then transferred to the polythene rod. Now the polythene rod has been charge by friction.For proof... after it has been charged,place the polythene rod next to some *very small bits of paper and see what happens.
Why does polythene have a positive charge with a cloth?
Polythene acquires a positive charge when rubbed with a cloth due to the triboelectric effect, where electrons are transferred from one material to another. In this case, the cloth tends to lose electrons to the polythene, resulting in the polythene becoming positively charged. The friction between the two materials facilitates this transfer, causing the imbalance of charge. Thus, the polythene ends up with a net positive charge while the cloth becomes negatively charged.
When polythene is rubbed with wool why does the polythene becomes negatively charged?
When polythene is rubbed with wool, electrons are transferred from the wool to the polythene due to differences in their electronegativities. The polythene gains extra electrons, making it negatively charged, while the wool becomes positively charged due to losing electrons.
Will a piece of perspex attract a polythene rod?
Yes, perspex can become attracted to a polythene rod when rubbed together due to the transfer of electrons between the two materials, resulting in a temporary static charge.
What type of charge does glass have when it is rubbed?
When glass is rubbed, it tends to acquire a negative charge. This is due to the transfer of electrons from the material it is rubbed against to the glass, causing an imbalance in charge and resulting in a negative charge on the glass.
What kind of charge is the cloth left with when rubbed against perspex?
The cloth is left with a negative charge when rubbed against perspex due to transfer of electrons from the perspex to the cloth.
When a polythene rod is rubbed with a duster it becomes negatively charged . why?
When polythene is rubbed with a duster, electrons from the duster are transferred to the polythene rod, giving the rod an excess of electrons and making it negatively charged. This transfer of electrons creates an imbalance of positive and negative charges on the surfaces, resulting in the rod becoming negatively charged.
What happens when polythene is rubbed with steel spoon?
it attrarts paper :P
