I'll try to answer what I think you were trying to ask.
Different elements are different substances. Technically, different isotopes are different substances as well, but in practice the chemical differences between two isotopes of the same material are much smaller than the differences between two different elements.
All elements (and nearly all compounds) undergo state changes.

What are two physical properties that can vary even when the substance with these properties dose not change?
The density and state of matter (solid, liquid, or gas) of a substance can change with changes in external conditions even in the absence of any change in the substance itself.
Does a change in state mean that a new substance has formed?
In a "physical change" a new substance is not created. In a "chemical change" a new substance is created. This applies to changes in states of matter. For example, ice, water, and steam are all the same substance, even though they exist in three different states. The elements of which they are comprised do not change. Sometimes you may be able to precipitate elements out of a substance through a phase change. In a mixture of alcohol and water you can fairly quickly boil out the alcohol.
What is the simplest type of substance you know of?
The simplest type of substance is an element. They cannot be split up even by chemical reactions. There are over 100 elements, and the Periodic Table is a list of them.
What type of change results in a change of state?
Shifting temperature. If its colder, the harder it will get because the particles will compress together. If its warmer, the substance will liquify (melt) or even turn into gas because the particles move apart from each other.
What elements are contained in a cancer atom?
There is no such thing as a cancer atom as cancer is not an element or even a substance. Cancer is a disease. An atom can belong to only one element and cannot contain others.
Are the atoms in a substance the same if the substance changes states?
On heating there will be a change in the physical state not chemical composition. So the number of atoms will be the same even after change in state.
What is a change of state-science?
Changes in state can occur when a substance is heated, cooled or even if an external pressure change occurs.
What are two physical properties that can vary even when the substance with these properties dose not change?
The density and state of matter (solid, liquid, or gas) of a substance can change with changes in external conditions even in the absence of any change in the substance itself.
What are two physical properties that can vary even when the substance with these properties does not change?
i think Buoyancy and Density are two physical properties that can vary even when the substance with these properties doesn't change.

Is the melting point of a substance considered a chemical property?
It just means that one liquid can be distinguished from another by its boiling point because it is a characteristic or property of that particular liquid.
Is fire a basic element?
It is in classical mythology, but not in reality. In reality fire is not even a substance but a chemical reaction between oxygen and some flammable substance.
Are iodine crystals homogenous?
Iodine is an element, so a pure substance, not a mixture, (so even not homogeneous).
Is apple juice a element or compound or nether?
its an element. an element is a pure substance. apple juice is a pure substance since it doesn't have other chemicals and such in it orange juice is not since its got all that pulp stuff in it, even without the pulp its still thick.
Are iodine crystals homogeneous mixtures?
Iodine is an element, so a pure substance, not a mixture, (so even not homogeneous).
Is iodine and water homogeneous or heterogeneous?
They are homogeneous. But they are not a mixture, so they are a pure substance
Is hydrogen peroxide a pure substance or a mixture?
Mixture, because it is mixed with all sorts of chemicals, such as smog, and or pollen.Mixture is NOT a pure substance, because to be a pure substance, it can't be mixed with anything.
