Chemistry Exam 1 Part 1

stored energy

study of the elements and their reactions

changing states from solid to gas, skips liquid state

a measure of the gravitational attraction of the earth for the body

characteristics that are observed only when the substance is interacting with other substances

the energy motion

releases heat (feels hot)

the physical change from a liquid to a gas 

study of those physical and chemical changes in the human body that are caused by the process of death

the energy that causes there to be changes in matter, measured in calories

properties that can change without involving a change in chemical composition

has no definite shape but does have a definite volume

anything that occupies space and possesses mass

basic unit of volume

having the quality of being easily converted at a relatively low temperature from the liquid to the gaseous state 

the movement of molecules from an area of higher concentration to an area of lower concentration

a measure of the quantity of matter a body contains

a change of state of matter from a liquid to a solid by the loss of heat 

1 gram = .0001 kilograms (1/1000 Kg)

the study of matter and the changes it undergoes

chemical processes involving dead organic substances in terms of decomposition, disinfection and preservation

the ability of a liquid or a gas to become firm and compact into a solid

the process by which a substance is given definite form

have no definite shape or volume, will always fill their container

Vaporization (when in terms of gas) is gas particles spreading further out

all the following are true about solids EXCEPT

Viscosity is resistance to flow

the formula for density is

absorbs heat (feels cool)

The metric system is based on the decimal system and has to do with multiples of 10

changes in the condition or state of a substance

changes that result in the formation of new substances

deals with compounds produced by living organisms; involves all the living processes in health & disease

the attraction of the molecules for each other at the surface of a liquid

a change in state of matter from a gas to a liquid 

the rapid passage of liquid particles to the vapor state by forming bubbles through the action of heat

select only the states of matter that relate to PHYSICAL properties

basic unit of length

The state of matter is dependent upon temperature and pressure

resistance to flow, affects the boiling and freezing points

chemistry of carbon and carbon containing compounds; chemistry of those things derived from living or once-living things

measures the intensity of heat, basic unit is degrees celsius

the ability or capacity to do work

energy associated with chemical reactions
