Matter Flashcards
Is a substance which occupies space and has mass
Matter
2 or more types of ATOMS that are NOT chemically combined
Mixture
Pure substance can be classified into two:
Elements and compounds
A substance that cannot be broken down into simpler by ordinary means
Elements
It is the smallest particle of an element
Atom
2 or more ELEMENTS chemically combined
Compounds
2 or more ATOMS chemically combined
Molecule
It is the smallest unit of compound
Molecule
It is smaller than atom
Quarks
Greek word of Atom
Atomos
what does Atomos means?
Indivisible particle
All atoms composed of?
Atoms in void
TRUE OR FALSE
A positively charged is cation and a negatively charged is anion
True
The size of an atom is measured in?
Angstroms
It magnify the image to 10 million times
Scanning Tunneling Microscope (STM)
It has a definite shape and volume
Solid
Solid can be classified into two, what are those?
Crystalline solid and Amorphous solid
This type of solid are well ordered
Crystalline solid
This type of solid are long range order
Amorphous solid
It has a fix volume but it does have a fixed shape
Liquid
What are the properties of liquids?
•Surface tension
•Viscosity
•Miscibity
To resist penetration
Surface tension
It can reduce the surface tension
Surfactant
The resistance to flow of a liquid
Viscosity
When a solid, liquid, and gas becomes solvent
Miscibity
This type of Miscibity dissolves each other
Miscible liquid
This type of Miscibity cannot dissolve each other
Immiscible liquids
It has no definite shape and volume
Gas
It is a change from one state of matter to another
Phase change
TRUE OR FALSE
Phase change are physical change
TRUE
Solid to Liquid =?
Melting
Liquid to Solid =?
Freezing
Liquid to Gas =?
Evaporation
This use in boiling point
Vaporization
Gas to Liquid =?
Condensation
Solid to Gas =?
Sublimation
Gas to Solid =?
Deposition
Change in physical appearance
Physical change
Chemical transformation of a chemical substance or there is a change chemically
Chemical change
Measured using numbers
Quantitative observations
Ability to shine
Colour/lustre
Ability to fold
Malleability
Ability to stretched
Ductility
Solid, liquid or gas at room temperature
State
How the surface of the substance feels
Texture
How the substance smell
Odour
ex. Sweet, salty, bitter, sour, spicy
Taste
ex. clear, transparent, translucent
Clarity
A regular pattern of 3d shapes
Crystal form
MP- solid to liquid
BP- liquid to solid
Melting and Boiling point
Ability to dissolve
solubility
Ability to resist being stretched
Hardness
Amount of matter in a substance
Mass
Amount of space a substance fits
Volume
The amount of mass in a given volume
Density
Ability to react with an acid
Reaction with acid
Ability of metal to react with air
Corrosion
Ability to react with oxygen
Combustibility
