|
Term
|
Definition
substances made up of two or more types of atoms that are chemically bonded together
has different characterstics than the elements that make it up
a chemical change is required to separate the individual parts from one another

Term
|
Definition
| properties that you can observe or measure without changing the composition of the matter |
|
|
Term
|
Definition
| properties that can only be observed when matter interacts with other matter and forms something new |
|
|
Term
|
Definition
state of matter in which the particles are moving relatively slowly due to their low amount of energy
particles are packed closely together in fixed positions
shape and volume do not depend on their container |
|
|
Term
|
Definition
phase of matter in which the particles have enough energy to slide past one another and change position
has a definite volume but shape changes with container |
|
|
Term
|
Definition
| state of matter that is comprised of ions and electrons that are produced when the atoms collide at great speeds and with great energy and break apart or fuse together |
|
|
Term
|
Definition
phase of matter in which the particles have so much energy that they are able to overcome attractions for one another and fill the space of their container
shape and volume depends on their container |
