Define Density
(1) |
The density of a material is its mass for a given volume.
Density = Mass/Volume |
|
|
|
Define Volume
(1) |
The amount of space an object occupies
|
Often measured in in milliliters or liters
|
|
|
Define Alkalinity
(1) |
a measurement of the quantity of chemicals present in water, that can neutralize acids. these chemicals include carbon dioxide, bicarbonate, carbonate and hydroxides.
|
the alkalinity of a stream indicates how well a stream can naturalize changes caused by acidic pollution.
|
|
|
Define Conductivity
(1) |
The ability of a material to transfer energy from one place to another.
|
|
|
|
Define Thermal Conductivity
(1) |
describes a substances ability to transmit heat
|
|
|
|
Define Electrical Conductivity
(1) |
describes a substances ability to transmit electrical current
|
|
|
|
What is a climatograph?
(6) |
a graph that shows the climate of a place.
it has two profiles: 1.) the bar graph shows precipitation over a period of time. 2.) the line graph shows the temperature during the same period of time. |
|
|
|
Tropical Forest Biome profile
(6) |
-Hot
-Wet climate - 60-160 inches of rainfall per year -has a dry season! -temperature is constant |
|
|
|
What is a covalent bond?
(7) |
a chemical bond formed by sharing of one or more electrons
|
Example: Cl2
|
|
|
What is a ionic bond?
(7) |
a chemical bond between two ions with opposite charges, characteristic of salts.
|
Example: NaCl
|
|
|
Comparing three cups (plastic glass, and styrofoam) of equal ice cold lemonade left for around 20 minutes, how are the puddles of water from the cups formed?
(8) |
The puddles of water are formed by air condensing on the cups due to the lower temperature of the cub compared to the surrounding room temperature.
|
|
|
|
Comparing three cups (plastic glass, and styrofoam) of equal ice cold lemonade left for around 20 minutes, which cup will have the largest puddle?
(8) |
the cup with the lowest temperature will have the largest puddle of water.
|
|
|
|
Which cup would be the better insulator - Glass, Plastic or Styrofoam?
(8,9) |
Styrofoam is the better insulator because it will produce the smallest puddle of water
|
|
|
|
What is an insulator?
(8) |
Materials that disrupt the free flow of electrons from atom to atom and molecule to molecule.
|
Example: Styrofoam
|
|
|
What is a conductor
(8) |
Conductors are materials which permit electrons to flow freely from atom to atom and molecule to molecule.
|
Examples: metals, salty solutions, water, the human body
|
|
|
What is thermal energy?
(8) |
heat. the energy portion of a system that increases with temperature.
|
|
|
