The Structure of Matter
Boiling Point
The temperature at which a liquid changes into a gas
Mass Number
One of the raw materials of a chemical reaction.
Ion
An atom or group of atoms with an electric charge.
Newton's first law of Motion
In the first law, an object will not change its motion unless a force acts on it.
Efficiency
The measure of how much work a machine does compared to the effort, or energy, used. An efficient machine has a higher mechanical advantage.
Frequency
The number of waves that pass a certain point in a given amount of time.
Covalent Bond
Chemical bond that shares the electron pairs between atoms.
Periodic Table.
A table the organizes the known elements into rows and columns by their properties. The rows running across are called periods. The elements are arranged in these rows in order of increasing atomic number. The columns running down are called groups or families. Each column lists a group of elements with similar chemical properties
Exothermic
Neutralize
To change acids and bases by chemical reactions into neutral products.
Newton's Second Law of Motion
In the second law, the force on an object is equal to its mass times its acceleration.
Effort Force
The force used to move an object
Reflection
The bouncing back of a wave that hits a surface just like light waves bounce off a mirror.
Ionic Bond
Donates an electron to the other atom.
Noble Gas is this:
Non metal
Endothermic
Reaction or process accompanied by or requiring the absorption of heat.
0-6 on PH Scale is:
Acid
Newton's Third Law of Motion
Newton's third law of motion states that for every action (force) in nature there is an equal and opposite reaction.
Mechanical Advantage
The mechanical advantage is the number of times a machine multiples the effort force.
Refraction
The bending of a wave caused by a change of speed as the wave moves from one type of matter to another.
Water. Made up of this.
Two hydrogen atoms and one oxygen atoms.
Chemical Property
The way in which an element acts with other elements
Product
During a chemical reaction, reactants are transformed into products.
8-14 on PH Scale is:
Base
Inertia
Inertia - the tendency of an object at rest to stay at rest and an object in motion to stay in motion in the same direction.
Effort Force
The force applied to the machine to make it work.
Trough
The low point of a transverse wave
Electron
Has a negative charge and orbits the nucleus
Non-metal
no metallic properties
Conservation of Mass
The law of conservation of mass states that mass is neither created nor destroyed by chemical reactions or physical transformations.
PH Level
Measure of the acidity or basicity of liquid solutions.
Unbalanced forces
The forces acting on an object that cause a change in velocity. The velocity of an object changes when the forces acting on it are unbalanced forces.
Resistance Force
The force resisting movement.
Wavelength
The distance between the crest on one wave and the crest on the next wave
