matter
|
anything that has mass and takes up volume
|
|
chemistry
|
is the study of matter - its composition, properties, and transformations
|
|
physical properties
|
are those that can be observed or measured without changing the composition of the material
|
|
chemical properties
|
are those that determine how a substance can be converted to another substance
|
|
pure substance
|
is composed of a single component and has a constant composition, regardless of the sample size and the origin of the sample. It cannot be broken down to other pure substances by any physical change.
|
|
mixture
|
is composed of more than one component. The composition of this can vary depending on the sample size. It can be separated into its components by physical change.
|
|
element
|
A pure substance that cannot be broken down into simpler substances by a chemical reaction
|
|
compound
|
a pure substance that formed by chemically combining (joining together) two or more elements

|
|
Conversion from Celsius to Fahrenheit
|
F = 1.8(C) + 32
|
|
Conversion from Fahrenheit to Celsius
|
C = (F - 32)/1.8
|
|
Conversion from Celsius to Kelvin
|
K = C + 273
|
|
Conversion from Kelvin to Celsius
|
C = K - 273
|
|
Density
|
a physical property that relates the mass of a substance to its volume
= mass (g) / volume (mL or cc) |
|
Specific Gravity
|
a quantity that compares the density of a substance with the density of water at the same temperature.
density of a substance (g/mL) / density of water (g/mL) |
