When polythene is exposed to heat, it softens and can ultimately melt. This is because the heat increases the kinetic energy of the polymer chains in polythene, allowing them to move more freely and weakening the overall structure of the material. Continued exposure to high heat can further break down the polymer chains and eventually lead to decomposition.
What else can I help you with?
Is polythene a poor conductor of heat and electricity?
Yes, polythene is a poor conductor of heat and electricity due to its molecular structure which does not allow for the easy flow of heat or electrons. This makes polythene an insulating material that is often used to protect against electrical currents and heat transfer.
What does shale turn into when its expossed to heat and pressure?
High pressure can cause the formation of the metamorphic rock slate from the sedimentary rock shale.
What happens when polythene is rubbed with steel spoon?
it attrarts paper :P
What happens when a polythene strip is rubbed on a woolen cloth and then placed near a thin stream of running water from a tap?
The polythene becomes negatively charged.
What is polythene rod made of?
The polymer "polythene".
What happens to metal when expossed to acid?
Corrosion occur with most metals.

What is the difference between Bakelite and polythene in nature?
Bakelite is a thermosetting plastic, meaning it cannot be reshaped once molded, while polythene is a thermoplastic that can be melted and reshaped multiple times. Bakelite is a poor conductor of electricity, whereas polythene is an insulator. Bakelite is more rigid and heat resistant compared to polythene.
Why is polythene called thermoplastic?
Polythene is also known as polyethylene. Polythene is a type of plastic that is widely used in packaging and many of the plastic products we use today. You see polythene in all shapes and sizes. Polythene is such a widely used product because it is easy to bend it and mold it into the shape that you want. This action of molding the plastic is called thermosetting. Polythene is heated to high temperatures and molded into the shape that is desired. Then the object is set aside and cooled. Once the object is at room temperature (or close to it) the object will not break or bend so readily. Now, if you take the prefix of thermosetting you just have "thermo." Thermo is typically used with words meaning temperature or heat. Because polythene is a plastic and it can be set in its shape by heat, it is called thermoplastic.
What is more flexible aluminium or polythene?
Polythene.
What is polythene rod made of?
The polymer "polythene".
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.
What are highly inflammable plastic- 1 polystyrene 2 Bakelite 3polythene?
Polystyrene is highly inflammable and releases toxic fumes when burned. Bakelite does not readily catch fire but can burn when exposed to high temperatures. Polythene is a thermoplastic that is highly flammable and can melt when subjected to heat, releasing hazardous fumes.
Is polythene a chemical?
Polyethene (polythene, polyethylene) is a chemical product.
