there are two types of change. the first one is the physical change. the form or appearance of the substance is change but the chemical properties of the substance is not changed. example, water evaporates into the air, that is a physical change because from liquid, water changes into gas but it then comes back to water as rain. the other one is chemical change wherein the chemical properties of the substance is changed. example is burning of wood. wood is burned and turned into charcoal. the chemical properties of wood is different from the chemical properties of charcoal and charcoal is another substance.
chemical
It is known as: conduction.
its density. note. density is often expressed as the ratio of the density of the substance to the density of water at standard temperature and pressure. This is known as the specific gravity of the substance. It is a dimensionless number so it has no units.
When one thing changes to another, the process is called metamorphosis. One dictionary definition is, "A marked change in appearance, character, condition, or function." This can happen with inanimate objects, as well as with biological entities. A good example is the butterfly.
The dependent variable.
"Specific gravity" or "specific density"
chemical .
Chemical properties
This is a chemical change, also known as a chemical reaction.
Mass gets preserved (you have to consider the stuff that isn't the end produced chemical, too). Otherwise, chemical changes are known for having different properties. They could have similar properties, I imagine, but then, "Why would anybody want to make them?"

substance
If the substance is an element the answer is an atom. If the substance is a compound the answer is a molecule.
A physical property can be observed without changing the material's composition. A chemical property can only be observed when a chemical change takes place.
The property that involves how a substance interacts with other substances is known as chemical property. This is what will cause chemical changes during reactions.
This phenomenon is called deposition.
reactivity, the tendency of an element to react with another substance is know n as its reactivity. the more the capacity of an element to react with another substance the more will be its reactivity, the series of elements arranged in their decreasing reactivity is known as reactivity series.
Through a process known as Sublimation
