What are Physical 4 Properties
100
- Mechanical Energy- amount of work an object can do based on its kinetic and potential energies. - Nuclear Energy: Energy that comes from the nucleus of an atom. - Thermal Energy- kinetic energy due to the movement of the particles that make up the object. - Electrical Energy- the energy of moving electrons. - Electromagnetic Energy- Energy is transmitted through space to form Electromagnetic waves. - Chemical Energy- is a form of Potential Energy, that depends on the arrangement of the atoms in a compound. - Sound Energy- caused by an object’s vibrations.
What is different forms of energy (7 types)
100
Atom- the whole thing Nucleus- the small positively charged dense center Protons- positively charged particle Neutron- neutrally charged particle Electron- negatively charged particle
What is the relationship between Atom, Nucleus, Proton, Neutron and Electron
100
Changes in Properties Precipitate Gas Production Color Change Release of Energy Absorption of Energy Light given off
What are Signs of a Chemical Reaction
200
energy that an object has because of its position, shape or condition.
What is Potential energy
200
Reactivity- ability to chemically react with other substances. Flammability- ability to burn. Oxidation- ability to rust. Density- amount of mass in a given amount of volume. Boiling point- the change in state from liquid to gas that occurs at a certain temperature. Melting point- the change of state from solid to liquid at a temperature. Solubility- the ability of one substance to dissolve in another at a given temperature. Electrical Conductivity- the measure of how well electricity can move through a substance. Thermal Conductivity- rate in which a substance transfers heat. Malleability- ability to be rolled or pounded into different shapes. Magnetism- ability to attract another substance. Ductility- able to be drawn out thin. State- condition of the substance.
What are some Chemical Properties and explain
200
- transfer of heat energy by direct contact of one particle to another. - transfer of heat energy by the circulation of a fluid. - transfer of energy by electromagnetic waves.
What is conduction, convection, and radiation.
200
equal to the number of the protons in the nucleus of the atom.
What is Atomic Number
200
- Release of energy - Take in energy
What are Exothermic and Endothermic reactions
300
the average of all the isotopes of that element, based on their percent occurrence in nature.
What is Atomic Mass
300
Change in shape or form and does not change the identity.
What is a Physical change
300
--> transfer energy/heat --> stop the flow of energy/heat
What is the significance of conductors and insulators in heat transfer.
300
bond that forms when electrons are transferred from one atom to another so that each ion has a full set of electrons in their outer energy layer.
What are Ionic Bonds
300
Temperature, Surface Area, Concentration, Catalysts and Inhibitors
What are ways change the rate of a Chemical Reaction (5)
400
must contain Carbon and Hydrogen, also may include other atoms
What is organic compounds
400
~~Components of a mixture are evenly distributed, hard to identify different components and separate. EX: koolaid ~~Not evenly distributed are easy to identify and separate. EX: sandwich
What is Homogeneous and Heterogenous
400
amount of energy needed to raise the temperature of 1 gram of water by 1 degree Celsius.
What is a calorie
400
- bonds with almost everything - in organic compounds - form rings
What is important about carbon
500
process of the nucleus of a radioactive isotope releasing a particle and energy; becoming a different isotope in the process.
What is Radioactive Decay
500
- Gravity/ Centrifuge- lets parts settle out - Filtration- filter traps larger sized particles - Magnetism- Magnets that attract magnetic minerals - Evaporation- Liquid Portion evaporates leaving solids - Distillation- Separates liquids with different boiling points. Heat mixture up until one becomes gas, remove gas and allow to cool and become liquid.
What is how to separate mixtures
500
the transfer of thermal energy from one object to another.
What is Heat
500
- bonds formed when atoms share one or more pairs of electrons. - form between nonmetals.
What are Covalent bonds
500
Fission- on earth, the splitting of a nucleus. Fusion- on the sun, joining of 2 nucleuses.
