QuestionAnswer
Chemistry Study of the nature of matter and changes matter undergos
Matter Anything that possesses mass and occupies space
What is the "nature of matter" Composition of a particular kind of matter, forces holding it together, observable properties
physical change and provide examples does not change chemical composition- ice to water
chemical change and provide examples results in the formation of new substance- decomposition, embalming, cremation
energy ability to do work
kinetic energy energy in motion- fluid moving through the body
potential energy stored energy- water at a closed damn
inorganic chemistry the study of compounds usually containing elements other then carbon
organic chemistry study of carbon compounds
biochemistry study of compounds produced by living organism
embalming chemistry study of changes in matter related to preserving & disinfection of a body
thanatochemistry study of physical and chemical change in the human body
Identify the common set of units used by all scientists Metric, SI
Standard unit of length meter
Standard unit unit of volume liter
Standard unit of mass kilogram
Standard unit of heat Calorie
Mega 10^6 M
Kilo 10^3 k
Deci 10^-1 d
Centi 10^-2 c
Milli 10^-3 m
Micro 10^-6 u
Nano 10^-9 n
Types of matter elements,compounds,mixture
states of matter solid,liquid,gas
ionic bonds transfers electrons
covalent bonds shared electron
4 class of compound Acid, bases, salt, oxides, electrolytes
methane simplest organic
law of conservation of matter matter cant be created nor destroyed
Physical Properties Characteristic that can be observed without altering chemical composition
Three typical states of matter melting.boiling,freezing
Melting point temperature at a given pressure changes from solid to liquid
Boiling point Liquid state to gaseous state
Solubility how much of something will dissolve in a given amount of water
density expresses the relationship between its mass and volume
Specific Gravity ratio of the mass of the substance to the mass of an equal volume of water at the same temperature
Chemical Property Characteristic that can be observed when substance is interacting with other forms of matter
