Chemistry: the study of…
properties of matter
interactions between matter
changes of matter
energy associated with those changes
Matter
anything that has mass and occupies space (i.e has volume)
Composition
specifies the types and amounts of simpler substances that make up a sample of matter
Substance
has definite, fixed composition, and distinct properties (i.e. either an element or a compound)
Mixture
is composed of a physical intermingling of two or more substances and whose composition is variable (i.e. might contain more, or less, of its various constituent substances) aqueous solutions
Macroscopic Properties
can be measured directly
Submicroscopic Properties
are deduced indirectly from microscopic measurements
We create models that relate to macroscopic measurements/ properties to microscopic properties
Consistently, understanding of the submicroscopic level properties helps us to account for and explain macroscopic behavior
The classification of matter is according to its…
Physical state and composition
Physical state
solid, liquid, gas
Composition
substance, mixture, homogeneous & heterogeneous
Kinetic Energy
is related to motion
Potential Energy
is related to the position in a force field
