Matter Matters
Anything that has mass and takes up space.
What is Matter?
Color, density, and boiling point are examples of this type of property.
Physical Property
This state of matter has a definite shape and definite volume.
solid
Solid → Liquid
Melting
The boiling point of water in degrees Celsius.
100°C
A substance made of only one type of atom.
Element
Flammability is this type of property.
Chemical Property
This state has a definite volume but takes the shape of its container.
Liquid
Liquid → Gas
Vaporization
Write 4,500 in scientific notation.
4.5 × 10³
Two or more elements chemically bonded together in a fixed proportion.
Compound
An ice cube melts into liquid water. Physical or chemical change?
Physical
This state has no definite shape and no definite volume.
Gas
Gas → Liquid
Condensation
Write 0.0062 in scientific notation.
What is 6.2 × 10⁻³
Salt water looks the same throughout, so it is this type of mixture.
homogeneous mixture
An iron nail forms rust. Physical or chemical change?
Chemical
This gas-like state of matter contains electrically charged particles.
Plasma
Solid → Gas without becoming a liquid first.
Sublimation (dry ice)
Convert 3.7 × 10⁵ into standard notation.
370,000?
Salad dressing which can separate and you can visibly see the different aspect of the dressing is an example of what type of mixture
heterogeneous Mixture
The best evidence that a chemical change has occurred is that this has formed.
new substance
According to Kinetic Molecular Theory, when temperature increases, this happens to particle movement.
They move faster
Gas → Solid without becoming a liquid first.
Deposition
Convert 8.4 × 10⁻⁴ into standard notation.
