TRANSCRIPT
What is S in the diagram?
Amplitude – the distance between a crest (or trough) and the rest position of the wave.
Radiation
Movement of Heat through Electromagnetic Waves.
Example: Solar Panels heating by Sunlight,
Popcorn popping in the Microwave.
Parts of a Circuit
Switch
An open switch does not allow the current to pass.
A closed switch does allow a current to pass.
Buoyancy
The force that causes less dense substances to float.
Less Dense = Floats
More Dense = Sinks
Atomic Number
The number of Protons in the nucleus of an atom.
Ex. The above atom has an atomic number of 4.
Atomic Mass
The number of Protons + Neutrons in the nucleus of an atom.
Ex. The above atom has an atomic mass of 9.
Compound
Two or more different substances chemically combined in a fixed ratio.
Example: Water, Salt, Carbon Dioxide
Physical Change
A change in matter that does not result in a new substance.
Example: Dissolving, Melting, Breaking, Boiling, Freezing.
Chemical Change
A change in matter that results in a new substance.
Example: Burning, Rusting, Corroding.
Law of Conservation of Mass
The mass of the products equals the mass of the reactants.
In an equation, the mass before the arrow equal the mass after the arrow.
Reactant
Matter that undergoes a chemical reaction.
Reactants are usually left of the arrow in a chemical equation.
Products
Matter that is the result of a chemical reaction.
Products are usually on the right of the arrow in chemical reaction.
Factors affecting Solubility (How much of a substance
dissolves.)
Agitation (Stirring)Surface Area (Smaller Pieces)
HeatPressure
Amount of SolventAmount of Solute
Solubility Rules
Like Dissolves Like(Polar dissolves Polar)
(Non-Polar dissolves Non-Polar)Example: Salt dissolves in water, Oil does
not dissolve in water. Oil is Non-Polar.
Solute & Solvent
The Solute dissolves in the Solvent
Example: In salt water, water is the solvent, salt is the solute.
