Matter & Properties Quiz Flashcards
Matter:
Something that has mass and takes up space
What are the four different states of matter?:
- Solid
- Liquid
- Gas
- Plasma
Describe a solid:
Solid – definite shape and volume
Describe a liquid:
Liquid – definite volume, indefinite shape
Describe a gas:
Gas – indefinite shape and volume
T/F – Gas and vapour are the same thing (if false, why?):
False, because vapour describes the gaseous state of a substance that is usually a liquid or a solid at room temperature
Describe plasma:
Plasma – very hot, electrons stripped away
Matter can be:
Matter:
•Mixture
•Pure Substance
In order to derive a pure substance from a mixture, what must be used?:
A form of physical separation must be implemented.
Give four examples of physical separation:
- filtration
- recrystallization
- distillation
- magnetism
A mixture can be:
Mixture:
•Heterogeneous
•Homogeneous
A pure substance can be:
Pure substance:
•Element
•Compound
What is a compound?:
A compound is 2 or more elements (chemically combined).
How would you derive an element from a compound?:
By making the compound undergo some sort of chemical change.
What does ‘Heterogeneous’ mean?:
A mixture with 2 phases (or more).
What does ‘Homogeneous’ mean?:
A mixture that consists of only one phase.
What is a physical property?:
Physical property – quality or condition of a substance that describes the matter. It can be observed or measured without changing the composition of that substance
What are six physical properties?:
- Odor
- Colour
- Density
- Solubility
- Melting point
- Boiling point
What are four physical properties referring to metals?:
- Conductivity
- Malleability
- Ductility
- Luster
Physical properties used to describe matter can be classified as ______ or _______:
Extensive or Intensive
Define intensive properties:
Intensive properties – depends on the type of matter present, not the amount
Give nine examples of an intensive property:
- Density
- Malleability
- Conductivity
- Ductility
- Luster
- Melting point
- Boiling point
- Colour
- Temperature
Define extensive properties:
Extensive properties – depends on the amount of matter in a sample
Give five examples of an extensive property:
- Mass
- Length
- Volume
- Shape
- Size
