What is the change of one substance into another substance?
A change from one or more substances to another is a chemical change.
What happens to a substance when the space between the substances particles increase?
When atoms are separated the substance changes forms. Solid Liquid Gas Plasma These are a few of the forms. The substance becomes more fluid, more easily shaped and compressed. It is able to form new materials, and is easier to ignite.

What happens to substances when they are heated?
When substances are heated, their molecules gain energy and move more rapidly. This increase in molecular motion can cause substances to change state (e.g. from solid to liquid), react with other substances, or decompose into simpler chemical components. Ultimately, heating a substance can lead to a variety of physical and chemical changes depending on the specific properties of the substance.
Is it true that if a physical change that occurs when a substance changes composition by forming one or more new substances?
No, that statement is incorrect. A physical change does not involve changing the composition of a substance or forming new substances. It only alters the physical state or appearance of a substance without changing its chemical composition. When a substance changes composition and forms new substances, it is considered a chemical change.
What happens to most substances when they are heated?
When substances are heated, typically their molecules gain energy and begin to move more rapidly. This increased movement can cause the substance to expand, change phase (from solid to liquid or gas), or even chemically react to form new substances. The specific changes depend on the substance's properties.
What type of reaction has occured when two or more substances combine to form another substance?
This is called synthesis, a combination chemical reaction that changes the chemical bonds in the substances.
What happens when particles of two or more substances are evenly mixed so they appear to be a single substance?
A homogeneous mixture is formed.
What type of reaction has occurred when two or more substance combine to form another substance?
This is called synthesis, a combination chemical reaction that changes the chemical bonds in the substances.
Is a chemical change a physical blend of two or more components?
No. A chemical change is when the chemical identity of substance or set of substances changes to a new substance or set of substances. Physically blending or mixing two components is a physical change.
What happens to the molecular level when substances get hot?
When substances get hot, the molecules gain energy and vibrate more rapidly. This increase in molecular motion causes the substance to expand, changing its physical state (e.g. from solid to liquid or from liquid to gas) if the heating continues. Heating can also break the bonds between molecules, leading to chemical reactions and changes in the substance's properties.
What is a pure substance made up two or more substances?
A mixture is a substance made up of two or more pure substances.
