a chemical reaction.
physical change
Chemical change.
A chemical change produces a new substance with different chemical properties from the original substances. This change involves the breaking and forming of chemical bonds. Examples of chemical changes include burning wood, baking a cake, and rusting of iron.
A chemical change of the original substance into one or more new substances is called a chemical reaction. During a chemical reaction, bonds between atoms are broken and new bonds are formed, resulting in the creation of new substances with different properties.
This could refer to a chemical transformation (chemical change), a chemical reaction, or spontaneous change. Some changes require another substance or substances to be mixed together. Some reactions will occur by themselves without any outside manipulation or stimulation.

Chemical change.
When a substance changes but still retains its original properties, the change is called a physical change. If it didn't retain its original properties, then it went through a chemical change.
It is called a compound.
heat
These are called Chemical Properties.
This temperature is called melting point and is different for each substance or material.
