Explanation:

Dude , u haven't mentioned the options anywhere so i think the above would do .

Hope it works ! Mark me the brainliest !!!

Answer 2

Option (d). Polystyrene is the material used to make such plates. Plate made of polystyrene can get softened on placing a hot pancake and hardened after some time.

The explanation for the answer:

Option(d):

• Polystyrene is a type of thermoplastic polymer. It is made by linking the monomers.
• This means it is formed as a result of polymerization. It is formed by linking the monomer styrene.
• They are hard and brittle and melt on heating. And gets hardened on cooling.

Option (a):

• Melamine is the most widely used plastic material. It is used for making kitchen utensils. Utensils made of melamine are harder and more durable.

Option(b):

• Polyurethane is a type of polymer.
• It is made by linking the urethane.
• It is mostly used for construction and building purposes.

Option(c):

• Bakelite is a type of thermosetting plastic. It is made by the condensation reaction of formaldehyde and phenol. It is hard and durable.
• It is mostly used in making electrical or switchboards as bakelite are poor conductors of electricity.
