What else can I help you with?
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.
If you rub a copper rod rather than a polythene rod the copper rod will not stay charged why not?
Copper is a good conductor of electricity, so when it is rubbed, any charge accumulated on its surface quickly redistributes throughout the rod and dissipates. This rapid conduction of charge prevents the copper rod from retaining a net charge like a polythene rod, which is an insulator and can hold onto excess charge more effectively.
Is polythene man made?
Yes, polythene is a man-made material. It is a type of plastic that is produced from ethylene, a chemical derived from petroleum.
Is polythene natural?
Polythene, also known as polyethylene, is a synthetic polymer made from ethylene, a compound derived from natural gas and petroleum. It is not a natural material as it is man-made through chemical processes in industry.
What is the monomer use to make polythene?
This monomer is ethene (or ethylene) - C2H4.
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.
What is a polythene rod?
A polythene rod is a rod made from polyethylene, a type of plastic known for its flexibility, high chemical resistance, and low electrical conductivity. It is commonly used in various applications such as insulation, packaging, and manufacturing of plastic products.
What charge is on a polythene rod?
A polythene rod can acquire a negative charge when it gains extra electrons through friction with another material.
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.
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.
Will a charged polythene rod repel or attract paper?
A charged polythene rod will attract paper. When the rod is charged, it develops an electric field that exerts a force on the charged particles in the paper, causing the paper to be attracted to the rod.
What happen when a polythene rod is rubbed with a cloth?
When a polythene rod is rubbed with a cloth, electrons are transferred between the two materials, causing the polythene rod to become negatively charged and the cloth to become positively charged. This results in the attraction between the two materials due to opposite charges.
What happens when you rub a piece of cloth with a polythene rod?
Rubbing a piece of cloth with a polythene rod transfers electrons from one material to the other due to friction. This causes the cloth to become negatively charged and the polythene rod to become positively charged, leading to the attraction between them due to opposite charges.
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.
If you rub a copper rod rather than a polythene rod the copper rod will not stay charged why not?
Copper is a good conductor of electricity, so when it is rubbed, any charge accumulated on its surface quickly redistributes throughout the rod and dissipates. This rapid conduction of charge prevents the copper rod from retaining a net charge like a polythene rod, which is an insulator and can hold onto excess charge more effectively.
What happens when a perspex rod is held near a polythene rod?
When a perspex rod is held near a polythene rod, the two rods will interact due to static electricity. If the perspex rod is positively charged (after being rubbed with a cloth), it will attract the negatively charged polythene rod, which has gained electrons. This attraction occurs because opposite charges attract, resulting in an electrostatic force between the two rods. If both rods are similarly charged, they will repel each other.
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.
