1. Density Equation Density (D) = mass (m) volume (v)

3. Using the equipment at your lab table find the density (g/cm3 or g/mL) of: - the block - the marble - water
While collecting data be thinking about:
the hypothesis
the procedure
the IV, DV, constants, etc.

4. Extensive Properties Intensive Properties
The physical properties of a substance are the characteristics of a substance that can be used to describe it.
There are two types of physical properties:
Extensive Properties
Intensive Properties
Extensive properties are directly related to the size/amount of a sample.
Intensive properties are NOT related to the size or amount of a sample.

5. There are 3 primary extensive properties that are related to the size of a sample.
Mass is related to the amount of matter in a substance. A larger sample has more matter, so mass is an extensive property.

6. Volume is the amount of space a sample occupies
Volume is the amount of space a sample occupies. A smaller sample would take up less space, so volume is an extensive property.

7. Length is simply how long a sample is
Length is simply how long a sample is. (Width and height are also just lengths.) Length measures the size of a sample, so it is also an extensive property.

8. Approximately 1 mole of Si
There are also three secondary extensive properties that are directly related to the mass of a sample.
28.1 grams of silicon
Approximately 1 mole of Si
The number of moles of a sample is also a measurement of the amount of matter. We will learn to convert between grams and moles a little later in the year.

9. Gravitational Potential Energy
Kinetic Energy
Gravitational Potential Energy
The amount of energy in a sample is directly related to its size. The amount of potential and kinetic energy of an object is directly related to the size and mass of that object.

10. Silicon
Water
Sodium Chloride
Atom
Molecules
Ions
The number of particles is also directly related to grams and moles of a sample. A larger sample has more mass which means more atoms, molecules or ions.

13. What type of physical property is density?

14. Density is an INTENSIVE property
Mass = g
Volume = 13.0 cm3
Mass = 8.75 g
Volume = 6.50 cm3
Mass = 35.0 g
Volume = 26.0 cm3
Density =
1.35 g/cm3
Density =
1.35 g/cm3
Density =
1.35 g/cm3
Because it is the relationship between mass and volume, it is independent of both. That makes density an intensive property.
