Ice cream from a solid to a liquid is melting, while from a liquid to a solid is freezing. Both of these are physical changes.
It is false. When a physical change takes place, the colors, texture, brittleness will change.
When a physical change takes place, a certain element or chemical will change its shape and in many cases, the volume too. Water takes the shape of the mold casing once it freezes.
The melting of the wax is a physical change. The burning the of wick is the chemical change
The chemical nature/identity of the substance stays the same when a physical change takes place.
Okay now here goes in a physical change no chemical reaction takes place. in chemical change chemical reactions take place. A physical change is reversible but a chemical change is not.In a physical change no new substance is formed(A+B=B) in a chemical change new substances are formed(A+B=C)
No. It is purely a physical change, that of melting. No chemical reaction takes place.
It is false. When a physical change takes place, the colors, texture, brittleness will change.
I assume you mean chemical "change" and the answer is no, it is a physical change that takes place.
Physical
When a physical change takes place, a certain element or chemical will change its shape and in many cases, the volume too. Water takes the shape of the mold casing once it freezes.

Sawdust is part of a physical change that takes place when wood is sawed.
physical and irreversible
The chemical nature/identity of the substance stays the same when a physical change takes place.
A phase change.
Dissolving salt in water is an example of a physical change. Although the ions of sodium and chlorine separate when the salt dissolves, no chemical reaction takes place.
I am looking into it and let you know as soon as I decide.
