100
Anything that has mass and volume.
What is Matter
100
Melting point- Temp at which a substance changes from solid to liquid Boiling point- Temp at which a substance changes from liquid to gas State- The physical form in which a substance exists (solid, liquid gas)
What is Physical Properties
100
Energy of an object that is due to the object’s motion. (All moving things have Kinetic Energy.)
What is Kinetic Energy
100
Single unit of an element.
What is an Atom
100
Molecules composed of the same repeating small groups of atoms joined together in long chains; A large molecule that is formed by more than 5 monomers, or small units.
What is Polymers
200
The ability to work.
What is Energy
200
Occurs when one or more substances are changed into new substances that have new and different properties.
What is Chemical Change
200
Energy that an object has because of its position, shape or condition.
What is Potential Energy
200
Center of the atom.
What is the Nucleus
200
Chemical reactions that requires an input of energy; A chemical reaction that requires energy input, usually as heat.
What is Endothermic Reaction
300
Force of attraction that holds atoms or ions together.
What is Chemical Bonds
300
Mass can not be created nor destroyed.
What is The Law of Conservation of Mass
300
Energy transmitted through space in the form of electromagnetic waves caused by the vibration of electrically charged particles. A type of kinetic energy (ex: sunlight)
What is Electromagnetic Energy
300
Mass of the Neutron + The mass of the Proton, expressed in atomic units.
What is Atomic Mass
300
The process in which atoms are rearranged to produce new substances; The process in which atoms are rearranged and chemical bonds are broken and formed to produce a chemical change of a substance.
What is Chemical Reaction
400
A chemical compound that us composed of carbon, hydrogen, and other elements; A covalently bonded compound that contains carbon.
What is an Organic Compound
400
When the two substances are easily identified, and can be removed ie. (Sandwich)
What is Heterogeneous Mixtures
400
The total energy of the particle motion of atoms in a substance. A type of kinetic energy (ex: hot water)
What is Thermal Energy
400
The Number of Protons in the Nucleus.
What is Atomic Number
400
Chemical reactions in which energy is released to the surroundings; A chemical reaction in which energy is released to the surroundings, usually as heat.
What is Exothermic Reaction
500
An ion that is made of more than one atom.
What is Polyatomic Ion
500
Gravity / Centrifuge- Lets parts settle out. Filtration- Filter traps larger sized particles. Magnetism- Magnets can attract magnetic minerals. Evaporation- Liquid portion evaporates leaving solids. Distillation- Separate liquids with different boiling points. Heat mixture up until one becomes a gas, remove gas and allow to cool and become a liquid.
What is Metheds Used to Separate Mixtures
500
Energy caused by the vibration of particles; it can travel through any state of matter. A type of kinetic energy (ex: music)
What is Sound Energy
500
Elements that are shiny and are good conductors of heat & electricity. Largest class of elements, located on left side of PT.
What is Metals
500
The nuclear reaction in which a large, unstable nucleus breaks into 2 smaller nuclei; The process by which the nucleus of a heavy atom splits into 2 or more fragments, the process releases neutrons and energy.
What is Nuclear Fission
