Macroscopic
Properties that cannot be observed by the five human senses
Microscopic
What are the five human senses?
Sight, Smell, Touch, Hear. Taste
Measure of mass per unit of volume
Density
Why do solids sink in liquids?
Because solids are more packed than liquids
What are individual pieces of crystalline solids called?
Crystals
A solid whose atoms, ions, or molecules are arranged in an orderly; Geometric and three dimensional structure
Crystalline Solids
Consists of positive metal ions surrounded by a sea of mobile electrons
Metallic Solids
What do mobile electrons do to metals?
Malleable and Ductile
What does the word ‘Malleable’ mean?
Can be hammered into shapes
What does the word ‘Ductile’ mean?
Easily drawn into wires
Mobile electrons make metals good conductors of ____ and ____

The particles are not arranged in a regular, repeating pattern.
Amorphous Solids
What does the word ‘Amorphous’ mean?
Without Shape
The ability to flow
Fluidity
Gasses and liquids are classified as ___
Fluids
Measure of resistance of a liquid to flow
Viscosity
If there is an increase of temperature, there is an increase in ___
Kinetic Energy
the energy required to increase the surface area of a liquid by a given amount
Surface Tension
Compounds that lowers the surface tension of water
Surfactants
The force of attraction between identical molecules
Cohesion
The force of attraction between different molecules
Adhesion
A liquid with a constant volume varies according to the weight, hence the greater the weight, the higher the ___
Density
This state of matter does not have a definite volume
Gas
The space is where the molecules move freely
Volume
The volume of gas is measured using a?
Burette
Movement of the molecules exerts a force over the area known as
