Question:
Intensive property.

Answer:
Properties independent of mass. Examples: density, specific heat, equivalent weight



Question:
Extensive property.

Answer:
Properties dependent of mass. Example: volume and mass



Question:
Volume of a cylinder.

Answer:
V = pi(r)^2h



Question:
Mass of water displaced by a rock with 143g in air and 82 g in water.

,Answer:
Mass of water displaced = Mass of rock in air - mass of rock in water



Question:
Volume of water displaced by a rock.

Answer:
V = mass of water displaced divided by density of water



Question:
Density of rock with 143g in air, 82 g in water.

Answer:
= mass of rock in air divided by the volume it displaces in water



Question:
If a piece of PVC is suspended in solution than the density of the PVC is.

Answer:
equal to the density of the solution



Question:
Which has a greater density: water or ice?

Answer:

Question:
What property of adipic acid is used in the separation during the adipic acid lab?

Answer:
solubility



Question:
What is the formula for Adipic Acid?

Answer:
H2C6H8O4

, Question:
What is the unit of specific heat?

Answer:
there is no unit



Question:
What does density tell us?

Answer:
Density relates information on how the atoms or molecules that make it up are arranged in space.
Substance with larger density is more tightly packed than the substance with smaller one.



Question:
What is the structure of adipic acid?

Answer:
HOOCCH2CH2CH2CH2COOH



Question:
What is adipic acid used for?

Answer:
Production of nylon; additive to drinks



Question:
Solubility of Adipic Acid.

Answer:
Adipic acid's solubility is temperature dependent. It is more soluble in hot water and slightly soluble
in cold water. This property is the principle of recrystallization of adipic acid.
