Element |
Basic building block of matter; cannot be broken down to a simpler substances; consists of atoms of only one type.
|
|
|
Atom |
The smallest particle of an element that has chemical properties of that element. These are the building blocks of matter |
|
|
Density |
A measurement of how solid something is, specifically it is the mass per unit volume of a substance (D=m/v)
|
|
|
Mass |
The amount of matter in a substance. you can mesure mass using a balance. This is not to be confused with matter
|
|
|
volume |
The amount of space an object takes up
|
|
|
matter |
anything that has mass and takes up space |
|
|
nuclueus |
the center of the atom that contains both protons and neutrons
|
|
|
Protons |
the positively charged particles of an atom; found in the nucleus
|
|
|
Newtrons |
The smallest particle of an atom that carries a neutral charge; found in the nucleus
|
|
|
electrons |
The negatively charged particles of an atom; found outside the nucleus
|
|
|
Periodic table |
a chart that contains all the known elements; arranged by the atomic number
|
|
|
Solid |
The state in which matter maintains a fixed volume and shape |
|
|
Liquid |
The state in which matter maintains fixed volume but adapts to the shape of its container |
|
|
Gas |
The state in which matter expands to occupy whatever volume is available |
|
|
physical property |
Characteristics that you can see through direct observation that includes color,texture,density,odor,luster and state (solid liquid and gas) |
|
|
chemical property |
Properties that can be only be observed when one be observed when one substance changes int a different substance |
|
|
physical change |
a change from one state (solid liquid gas) to another without change a chemical composition |
|
|
chemical change |
Results in the formation of one or more new substances: a change that cannot be reversed.
|
|
|
melting |
change of state from a solid to a liquid with the addition of energy
|
|
|
evaporation |
the change of a substance from a liquid to a gas
|
|
|
Boiling |
the conversion of a liquid to a vapor
|
|
|
freezing |
The change of state from liquid to solid
|
|
|
condenstation |
the change of state of gas to liquid
|
|
|
sublimation |
the process in which a solid changes straight to a gas
|
|
|
conduction |
the transfer of heat energy between objects that are in contact or touching
|
|
|
convection |
the transfer of heat energy by a moving liquid or gas
|
|
|
radiation |
the transfer of heat energy by electromagnetic waves
|
|
|
thermal energy |
the total of all the kinetic and potential energy of the atoms of an object
|
|
|
tempature |
the measure of thermal energy
|
|
|
insulator |
a material that does not let thermal energy or electricity pass through easily
|
