What are the three most common states of matter? |
Solid, Liquid, and Gas |
|
The particles that make up matter are in constant ______________. |
Motion |
|
Matter is made up of two kinds of particles: ____________ and ___________. |
Atoms and molecules |
|
No definite shape or volume |
Gas |
|
Has a definite volume and takes shape of its container |
Liquid |
|
Has a definite shape and volume |
Solid |
|
The most common state of matter in the world |
Plasma |
|
These solids have a very orderly, three-dimensional arrangement of particles in a repeating pattern |
Crystalline |
|
These solids have particles that are not arranged in a pattern. |
Amorphous |
|
A force that acts on particles of a liquid. Makes the particles "clump" together and is the reason dew forms on grass in the morning. |
Surface Tension |
|
Water has a higher surface tension than oil. Explain what that means? |
Water particles clump together easier than gasoline. |
|
A liquid's resistance to flow. |
Viscosity. |
|
A liquid that has tiny particles of a solid suspended in it. |
Colloid. |
|
What is the most common colloid? Hint - Three letters. |
Gel |
|
Is gas a fluid? |
Yes |
|
Where will you find gas in the body? |
Air in the lungs |
|
Where will you find liquid in the body? |
Water, blood. |
|
Where will you find a solid in the body? |
Bones |
|
Almost all matter ________ when it gets hotter and __________ contracts when it gets cooler. Hint - Opposites |
Expands, contracts |
|
Liquids are fluid, but not ___________. |
Compressible |
|
Why is ice less dense than water? How can you tell? |
When ice freezes it becomes less dense and changes volume. The particles inside contract and make the ice be able to float in water. |
|
A measure of how fast particles in an object are moving. |
Temperature |
|
The amount of space an object takes up. |
Volume |
|
Particles of gas can be ___________. |
Compressed. |
|
The amount of force exerted on a given area of surface. |
Pressure |
|
Boyle's Law states that there is an inverse relationship between the pressure and volume of a gas. So, if you decrease the volume of a container of a gas, the pressure will increase. The temperature is constant. |
READ OVER THIS AS MANY TIMES AS POSSIBLE. |
|
Charles' Law states that the temperature of a gas increases with an increase in volume. The pressure is constant. |
FREAKING MEMORIZE THIS. |
|
What does 'scuba' mean? |
Self Contained Underwater Breathing Apparatus |
|
What are air thermometers usually filled with? |
Mercury or Colored Alcohol |
|
What was the flammable gas that caused the Hindenburg to explode? |
Hydrogen |
|
What was the date of the Hindenburg crash? |
May 6, 1937 |
|
What is the SI unit for pressure? |
Pascal (Pa) |
|
What are the five major changes in state? |
Melting, freezing, evaporating, condensation, and sublimating |
|
The particles in liquid have more __________ than particles in ice. |
Energy |
|
The particles in steam have more _____________ than particles in liquid water. |
Energy |
|
To change a substance from one state to another heat must be added or __________. |
Removed. |
|
An Endothermic reaction occurs when energy is gained by a substance. |
An Exothermic reaction occurs when energy is removed from a substance. |
|
Melting (heat is getting added). Endo or Exo? |
Endo. |
|
Freezing (heat is getting taken away). Endo or Exo? |
Exo. |
|
(Endo (In) thermic (Heat)) |
(Exo (out) thermic (heat)) |
|
Is gallium (Ga) a metal? |
Yes |
|
What is unique about gallium? |
Because of it's low-melting point it is able to melt in your hand, and turn back into a solid in a matter of minutes. |
|
Is mercury (Hg) a metal? |
Yes |
|
What is unique about Mercury? |
It is always a metal and it is able to be broken up into smaller particles, or pieces. |
|
The change of a liquid to vapor, or gas, throughout the liquid. |
Boiling |
|
At which temperature (Celsius) does water normally boil at? |
100 degrees Celsius |
|
At which temperature (Celsius) does water boil at in Denver, Colorado? Why? |
95 degrees Celsius; Because the pressure is lessened at a higher altitude. |
|
What elements are found in antiperspirant? |
Aluminum and zinc. |
|
What is carbon dioxide in a solid state called? |
Dry Ice |
|
The ___________ Theory of Matter explains change in state. |
Kinetic. |
|
Is ice able to get colder once it freezes? |
Yes, the particles are always able to get closer together. |
|
When a liquid evaporates, the molecules become a vapor a the surface only. When a liquid boils, the molecules become a vapor __________ the liquid. |
Throughout the liquid |
