physical change. When sugar is heated, it changes from a solid to a liquid state without changing its chemical composition.
Thermoplastic is a polymer that can remelted and remolded many times.Thermoplastic is a polymer resin based plastic that softens/melts when heated.Thermoset-plastic is a polymer resin based plastic that polymerizes and/or crosslinks when heated, hardening it. If heated more it just chars.
Talc don't change the color if heated.
I know of nothing called a "thermostat polymer".Perhaps you meant "thermoset plastic", which undergoes polymerization and sets when heated.The other type is "thermoplastic" which is already polymerized and hard, but softens when heated.
The characteristic of matter you are referring to is called a physical property. The ability to melt is an example of a physical property exhibited by ice, where it changes from a solid state to a liquid state when heated.
Polyvinyl chloride (PVC) is a thermoplastic polymer, which means it can be heated and molded multiple times without undergoing a chemical change. This property makes PVC suitable for thermoforming processes where it is heated and shaped into desired forms.
That would be a chemical property demonstrated by a chemical change.
When solid is heated and melt then it will change into gas
No, it is a chemical change Iron turns green means it is oxidized to ferrous (Fe+2) state.

physical only, you are only changing its state, not its composition.
An example of a reversible change is an ice cube meting into water and then changing back to an ice cube again if frozen. Another is chocolate melting when heated and changing back to a solid when cooled.
