Classifying Matter
Describe matter
Anything that has mass and takes up space
A mixture that has its substances spread evenly throughout.
What is homogenous?
A definite shape and a definite volume.
What is a solid?
Liquid changing to solid.
What is freezing?
State 3 general types of elements
Metals, Nonmetals, and Metalloids
State two things matter can exist as
Pure Substance or Mixture
A mixture whose substances are NOT spread evenly throughout.
What is heterogeneous?
A definite volume, but no definite shape.
What is a liquid?
Solid changing to liquid.
What is melting?
What type of element is brittle and found on the right hand side of the table?
What is a nonmetal?
Different types of atoms combined chemically.
What is a compound?
Tea and salt water are examples of this type of mixture.
No definite shape or volume.
What is a gas?
Liquid changing to gas one layer at a time.
What is evaporation?
What type of element is a good conductor of electricity and are mostly solids.
What are metals?
A variety of compounds and elements that are not combined chemically.
What are mixtures?
Minestrone (Vegetable soup) is an example of this
What is a Heterogeneous Mixture?
All matter is made up of atoms and particles that are always in motion
Gas turning to liquid.
What is condensation?
State what type of element is Tungsten and describe a property of Tungsten
It is a metal
(any property of metals)
Elements and compounds make up this classification.
What are pure substances?
BONUS: What kind of mixture is it?
It has components of colors that can be separated.
It is a homogeneous mixture
Describe the difference between HEAT and TEMPERATURE
Heat is Energy
Temperature is the measure of the kinetic energy (motion) of particles
A solid skipping the liquid phase and turning directly into a gas.
What is sublimation?
What type of element has the properties of a semiconductor?
What is a metalloid?
