No, the melting of plastic is not a chemical reaction. This is because there is just a temperature change, which happens to change solid to liquid. The solid remains the same element with the same properties, and no "new substance" is formed.

∙ 12y agoTrue melting is not a chemical reaction; instead it is a physical one. Many polymers, however can not truly melt, and if they are brought into a liquid state, a chemical reaction has occurred.
I'll put it simply. You see my friend, when a chemical reaction occurs, a new substance is formed. When you melt plastic, what's the result? Yes, it's still plastic. That means it's physically changed, not chemically. :3

∙ 9y agoMelting is more of a phyiscal change than a chemical one. The original substance and the product is chemically unchanged in the process. Pure ice (H2O) becomes water (H2O) on heating, which is, chemically speaking, the same substance.

∙ 14y agono,because even if it melts it's still ice cream .
no it is a physical change not a chemical change.
Wiki User
∙ 11y agoYes, because you can not change that tray back to its normal self again. It is a chemical change.
Wiki User
∙ 10y agoBurning of plastics is a chemical change because burning is a chemical reaction - oxidation (reaction with oxygen).

∙ 10y agoNo, it is a phase change.

How do you find the melting point of plastic?
by melting it
Is a melting point a chemical property?
melting is a physical property, not chemical property.
Is a plastic tray melting a physical or chemical change?
chemical change.because once the tray melts it's no longer there anymore
Is ice cream melting in a bowl a chemical change?
No. It is purely a physical change, that of melting. No chemical reaction takes place.
Is shortening melting a chemical change or chemical property?
Chemical prop

Why are chemical reactions that have equilibrium points close to completion preferable for manufacturing?
ans 1=when the rate of reverse reation become equals to rate of forward reaction,such chemical reation is in equilibrium
