What are the 3 phases of matter? |
-Solid -Liquid -Gas |
|
|
What are some properties of a solid? |
-Closely packed particles -Attractive force holds molecules together -Particles always vibrate in place **Definite Shape **Definite Volume |
|
|
What are some properties of a liquid? |
-Particles are in contact with each other -Attractive force holds molecules together -Particles slip past each other **Definite Shape **Definite Volume Have more kinetic energy than solids |
|
|
What are some properties of a gas? |
-Particles not in contact with each other -Enough energy to overcome attractive forces -Particles move randomly in a straight line and bounce off each other **No definite shape **No definite volume |
|
|
What is the difference between amorphous and crystalline solids? |
In crystalline solids, the particles are lined up in an orderly pattern and form, like a crystal. In amorphous solids, the particles are just smooshed together, like butter! |
|
|
What is viscosity? |
The resistance of liquid to flowing, like honey |
|
|
What is surface tension? |
The inward pull amongst water molecules that lets water drops maintain their shape |
|
|
What is the relationship between the phases of matter and the energy (movement) of the particles? |
When a solid, particles vibrate. When a liquid, particles slide past each other. When a gas, particles bounce off each other |
|
|
What is melting? |
The change in state from solid to liquid |
|
|
What is freezing? |
The change from a liquid to a solid |
|
|
What is vaporization? |
The change from a liquid to a gas |
|
|
Whats the difference between boiling and evaporation? |
boiling happens below as well as at the surface. Evaporation is only on the surface |
|
|
What is condensation? |
The change in state from a gas to a liquid |
|
|
What is sublimation? |
occurs when the surface particles of a solid gain enough energy that they form a gas |
|
|
What is a melting point? |
a characteristic temperature in which melting occurs. Solid⇨ liquid |
|
|
What is a freezing point? |
the temperature at which liquid turns to a solid |
|
|
What is a condensing point? |
the temperature at which gas turns to a liquid |
|
|
What is a boiling point? |
The temperature at which liquid boils. Liquid⇨ Gas |
|
|
What role does thermal energy play in the changing of matter from one state (phase) to another? |
You change the state by adding or taking away thermal energy |
|
|
According to Boyle's law, what is the relationship between pressure and volume? |
As pressure goes down, volume goes up. If volume goes down, pressure goes up |
|
|
What is the equation for Boyle's Law? |
P1V1=P2V2 |
|
|
According to Charles' law, what is the relationship between temperature and volume? |
When 1 goes up, the other goes up. When one goes down, the other goes down. |
|
|
What is the equation for Charles' Law? |
V1T2=V2T1 |
