Question | Answer |
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 |
