3. Physical Chemical  Physical changes are concerned with energy and states of matter. Physical change does not produce a new substance. Changes of state(melting, freezing, vaporization, condensation, sublimation,)are physical changes. EX:Crushing a can,melting an ice cube, breaking a bottle, cutting paper, and cutting wood  Chemical change is any change that results in the formation of chemical substances. Chemical change involves making or breaking of bonds between atoms. EX:Burning wood, burning paper, decaying animals, explosion of fireworks,and digestion of food.

5. Physical chemical  A physical property is an aspect of matter that can be observed or measured without changing it. Are properties that do not change the chemical nature of matter. EX:Color,smell,freezing point, boiling point, and melting point.  Chemical property may only be observed by changing the chemical identity of a substance. Are properties that do change the chemical nature. EX: heat of combustion, reactivity with water, PH, and electromotive force.

7.  An element is a type of matter composed of atoms that all have exactly the same positive charge on their nucli.All atoms of an element have the same atomic number. It is composed of identical atoms. An element is a substance that cannot be decomposed into simpler substances. EX:Iron,carbon,oxygen,sylcum,sileum.

8.  A compound is a pure substance composed of two or more substances that are chemically combined. In a compound a particle, is formed when atoms of two or more elements join together. EX:Table salt,water,sugar,carbon dixiode,and baking soda.

9.  Is that a substance is pure and is only made up of one particle. And it cannot be broken down using physical process.  Where a mixture is made up of more than one type of particle. And a mixture could be broken down using physical process.

10. Homogenous Heterogeneous  A Homogeneous is when two substances mix evenly. EX:Lemonade,salt and water,kool- aid,paint,and soda  A Heterogeneous is composed of different substances. EX:Salt water,cement,cottage cheeze,sald,m&m’s

11.  SOLUBILITY is an ability of a substance to dissolve. In the process of dissolving, the substance which is being dissolved is called a solute and the substance in which the solute is dissolved is called a solvent.Its when a solution mixes evenly.

12. solution  A solution is a mixture that appears to be a single substance, but is composed of particles of two or more substances.  Solute-The substance that is dissolved. EX:kool-aid  Solvent-The substance in which the solute is dissolved EX:water

13.  A periodic table is a table that demonstrates the different types of atoms. You use it to find an element that has a number of certain type of an atom. One of the pattern in a periodic table is that they’re sorted by states of matter and if they’re metal or non-metal.

14.  Atoms are made up of tiny bits of electricity, which are called protons,neutrons,and electrons. Protons have a positive charge, Electrons have a negative charge, and Neutrons have a neutral charge. Both protons and electrons are the nucleus of an atom. They are so small you cant see them, except with an electron microscope. Some atoms have more protons, neutrons and electrons and some have fewer. An atom behaves differently depending on how many protons a nod electrons it has.

15. SOLID:  A solid is one of the three states of matter. It is resistance to changes of shape, or volume. Unlike a liquid, a solid object does not flow to take the shape of its container, nor does it expand to fill the entire volume available to it like a gas does. The atoms in a solid are bounded to each other. Particles n a solid are tightly packed, which are usually in regular pattern. They also vibrate but generally do not move from place to placenta particles also don’t flow easily. EX: Ice, sand, wood, brick

16. LIQUID:  Liquids do not have a definite shape. It takes the shape of its container. Liquids can be flow,poured,and spilled. Particles in a liquid are close together with no regular arrangment.They vibrate, move about, and slide past each other. They also flow easily. EX:Syrup,rain,milk,water,honey,

17. GASES:  Gases do not keep their shape, they completely fill the container that their in flow with. They do not have a definite shape or a definite volume. They also have no color. The particles in a gas are well separated with no regular arrangment.They flow easily, they also vibrate and move easily at a high speed. EX:Steam,helium,air,bubbles,
