Because, it has no crosslinks therefore its molecules move more freely. On the other hand, some other polymers, such as Bakelite, are crosslinked and you cannot turn then into a liquid without breaking the covalent bond.
Yes
Potassium iodide, like salts in general, has a high melting point. It does not melt easily when heated.
Because! :)
i don't know tbh
It sure does and trickles down the candle
Thermoplastics become less viscous or melt when heated. such plastics may be recycled that means may be moulded into another shape on melting. Thermoset plastics do not - for instance melamine.
polythene bag has a higher melting point
Yes. Almost any plastic will melt when heated.
Marble will melt when heated sufficiently.
It will melt if heated hot enough.
it will melt
Yes
Yes, nearly all substances will melt if they are heated enough.
They melt..> they melt and turn back to water.
Yes, if the metals are heated up enough to melt.
