27
All samples of a given substance have the same intensive properties
Every sample has the same composition
28
Two categories used to classify physical changes
Reversible and Irreversible
29
Two categories used to classify properties of matter
Intensive and Extensive
30
How are mixtures classified?
Heterogeneous Mixtures; Homogeneous Mixtures
31
What type of properties can be used to separate mixtures?
particle size(Filtration), phase, solubility, and boiling point, magnetism. Property- Distillation, Filteration
32
The term phase as it relates to homogeneous and heterogeneous mixtures
phase in anything that has a uniform and definite composition (look in book)
33
How are a substance and a solution similar? How are they different?
Both substances and a solution have a uniform composition throughout. For differences, a substance has a definite composition where as a a solution has a variable composition and a mixture os substances.
34
How is a compound different from an element?
Compounds can be broken down into simpler substances by chemical means, but elements cannot.
35
How can you distinguish a substance from a mixture?
If the composition of a material is fixed, the material is a substance. If the composition of a material may vary, the material is a mixture.
36
What are chemical symbols and chemical formulas used for?
Chemical symbols to represent elements, and chemical formulas to represent compounds or a single element
37
Mass
The amount of matter in an object
38
Weight
The amount of gravitational on an object
39
Force
Causes thing to move
40
Difference between chemical and physical changes
Chemical change- changes the composition | Physical change- changes appearance
