What is polythene rod made of?
The polymer "polythene".
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.
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.
Does polythene dissolve in water?
No, polythene does not dissolve in water as it is a non-polar polymer and water is a polar solvent. This lack of attraction between the polythene molecules and water molecules prevents it from dissolving.
What is the difference between biodegradable polythene and ordinary polythene?
The main difference between Ordinary Polythene & Biodegradable polythene is: * Ordinary polythene takes an around 100 + years to degrade... * Biodegradable/Degradable polythene degrades or biodegrades in around 5 yrs depending on how it's made and how its disposed. However, biodegradation starts in the presence of sunlight, moisture, mechanical stress and/or microorganisms...

What are the types of polythene?
LDPE , HDPE, LLDPE
What are the types of polythene bags?
LDPE , HDPE, LLDPE
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 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.
Which state proposed a ban all types of polythene packing for the first time in India?
Himachal Pradesh
What is more flexible aluminium or polythene?
Polythene.
What is polythene rod made of?
The polymer "polythene".
Is polythene a chemical?
Polyethene (polythene, polyethylene) is a chemical product.
When was Polythene - album - created?
Polythene - album - was created in 1996.
Can polythene rubbed against steel spoon produce charge?
Yes, when polythene is rubbed against a steel spoon, the two materials become charged due to the transfer of electrons between them. The polythene gains a negative charge, while the steel spoon gains a positive charge.
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.

What happens when a steel spoon is rubbed with a polythene?
When a steel spoon is rubbed with polythene, the transfer of electrons can occur due to friction between the two materials. This results in the spoon becoming negatively charged, while the polythene becomes positively charged. This static electricity interaction causes the two materials to be attracted to each other.
