Element |
basic building block of matter; cannot be broken down to a simpler substances |
|
Atom |
The smallest particle of an element that has the chemical properties of that element. These are the building blocks of all matter. |
|
Mass |
the amount of matter in a substance. You can measure mass using a balance. This is not to be confused with weight. |
|
Density |
A measurement of how solid something is, specifically it is the mass per unit volume of a substance. (D=m/v) |
|
Volume |
The amount of space an object takes up. |
|
Matter |
anything that has mass and takes up space (has volume)
|
|
Nucleus |
the center of an atom that contains both protons and neutrons
|
|
protons |
the positively charged particles of an atom; found in nucleus
|
|
neutrons |
the small particle of an atom that carries a neutral charge; found in the nucleus |
|
electrons |
the negatively charged particles of a n 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 fixed shape |
|
liquid |
the state of which matter maintains a fixed volume but adapts in the shape of the container |
|
gas |
the state of matter in which matter expands to occupy whatever volume is available
|
|
physical property |
characteristics that you cans through direct observation that includes color, texture, density, odor, luster, and state (solid, liquid or gas) |
|
chemical properties |
properties that can only be observed when one substance changes into a different substance |
|
phyiscal change |
a change from one state (solid, liquid or gas) to another without a change in 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 a liquid to solid |
|
condensation |
the change of state from gas to a liquid |
|
sublimation |
the process in which a solid changes directly to a gas |
|
conduction |
the transfer of heat energy between objects that are in contact or touching |
|
convection |
the transfer if heat energy by a moving liquid or gas |
|
radiation |
the transfer of heat energy by electromagnetic waves |
|
thermal energy |
the total of all kinetic and potential energy of atoms in an object |
|
temperature |
the measure of thermal energy |
|
insulator |
a material that does not let thermal energy or electricity pass through easily |
