Chemistry
Subscript- Number placed to the lower right of a chemical symbol to indicate the number of atoms of the element in the compound. 
Chemical Equation- expression in which symbols, formulas, and numbers are used to represent a chemical reaction.
Chemical Formula- Combination of chemical symbols usually used to represent a compound.
-
Gas- an airlike fluid substance which expands freely to fill any space available, irrespective of its quantity.
Solid- firm and stable in shape; not liquid or fluid.
Liquid- a substance that flows freely but is of constant volume, having a consistency like that of water or oil.
-
Pure Substance- A substance made of only one kind of particle having definite properties and a definite chemical composition.
Atom- The smallest part of any element that retains all the properties of that element
Chemical Symbol- Shorthand way of representing an element.
Compound- A pure substance that contains two or more elements.
Coefficient- Number that is placed in front of a symbol or a formula in a chemical equation that indicates how many atoms or molecules of this substance are involved in the reaction.
Element- The simplest type of pure substance.
Molecule- The smallest part of any compound that retains all the properties of that compound.
Mixture- Matter that consists of 2 or more pure substances that are physical but not chemically combined
Balanced Equation- A chemical equation in which there is an equal amount of atoms of each element on each side of the equation demonstrating conservation of mass.
Chemical Reaction- Process in which the physical and chemical properties of the original substance changed as a new substance with different physical and chemical properties is formed.
Physical Change- Are changes affecting the form of a chemical substance, but not its chemical composition.
Phase Change- Are physical changes of a substance from one state (solid, liquid, or gas) to another without a change in its formula / composition
Chemical Change- are a usually irreversible chemical reactions involving the rearrangement of the atoms of one or more substances and a change in their chemical properties or composition, resulting in the formation of at least one new substance.
State- of matter is defined as one of the ways in which matter can interact with itself to form a homogeneous phase. Examples: solid, liquids, gases, plasma
-
Thermal Energy- comes from the kinetic energy of the molecules. As the kinetic energy (the motion) of the molecules increase, they will become 'hotter' and the molecule will have more thermal energy and vice versa.
Phase- is a physically distinctive form of matter, such as a solid, liquid, gas or plasma.
Chemical Property- any of a material's properties that becomes evident during, or after, a chemical reaction; that is, any quality that can be established only by changing a substance's chemical identity.
Chemical Change- Chemical changes are a usually irreversible chemical reactions involving the rearrangement of the atoms of one or more substances and a change in their chemical properties or composition, resulting in the formation of at least one new substance.
