|
Definition
| Solids have definite shapes and definite volumes. |
|
|
Term

Term
Describe a liquid.
(What kind of shape and volume do they have?) |
|
Definition
| Liquids have no definite shape, but they do have a definite volume. |
|
|
Term
| Describe how the atoms in a solid are arranged. |
|
Definition
| The atoms are packed very close together and are in an orderly arrangement. |
|
|
Term
| Describe how the atoms in a liquid are arranged. |
|
Definition
| The atoms are packed close together but in a random arranged. They slide past one another. |
|
|
Term
Describe a gas.
(What kind of shape and volume do they have?) |
|
Definition
| Gases have no definite shape and no definite volume (small amounts will always spread to fit it's container). |
|
|
Term
| Describe how the atoms in a gas are arranged. |
|
Definition
| There is a lot of space between gas atoms and they are at random locations within their container. |
|
|
Term
|
Definition
| Plasma is rare on Earth, but the most common type of matter in the universe. It exists at extremely high temperatures. |
|
|
Term
| What is the fifth state of matter and under what conditions can it exist? |
|
Definition
| Bose-Einstein Condensate, where the atom behaves as a single particle. It exists at extremely low temperatures (-273 C) |
|
|
Term
| What does the Kinetic Theory say about the motion of atoms? |
|
Definition
| All particles of matter are in constant motion. |
|
|
Term
True or False.
The particles of a gas are at rest. |
|
Definition
| False. The particles of a gas are moving the fastest. |
|
|
Term
| What can happen to the kinetic energy of two atoms when they collide? |
|
Definition
| One atom may lose energy and slow down, while the other atom may gain energy and speed up. |
|
|
Term
| There are forces of __________ among all particles in matter. |
|
Definition
| There are forces of attraction among all particles in matter. |
|
|
Term
| Under normal conditions, scientists can ignore the forces of attraction in a gas. Why? |
|
Definition
| Because the gas particles are apart and moving fast, so the forces are too weak to have an effect. |
|
|
Term
| What does the kinetic theory of gases say about a gas in a container? |
|
Definition
| The constant motion of gas allows it to always fill a container of any shape or size. |
