Answer:
Compare qualitative and quantitative physical properties. Use examples of properties listed in Tables 4.2 and .3 as part of your answer
can be observed and described without detailed measurement, usually obvious and easy to observe. For example, odor can be described as sweet, pungent and or moldy.
Quantitative Physical Properties
can be measured and assigned a value, for example melting points and boiling points could be considered a quantitative physical property
Why is the melting point considered a physical property?
Because you are not creating a new substance in the process of melting it. If you melt gold, it will still remain gold just in a different form.
What property determines the choice of material that is used for the inside of an electrical wire and the material that is used for the outside of the wire?
The conductivity of the material will determine the material needed for both the inside and outside of an electrical wire. The electrical wires ability to conduct electricity, or give off heat will allow us to have an idea as to what type of material may insulate or protect the electrical wire.
When might a large volume of material have little mass?
When the material weighs less. For example, Styrofoam with the volume of 500 cm (cubed) has a smaller mass in comparison to 500 cm (cubed) of Gold. Since the density in Styrofoam is little, the mass of it would also be little in contrast to an element like gold, which has a higher density therefore it has a higher mass.
Gold has a density of 19.3g/cm (cubed). Iron pyrite, commonly known as fool's gold because of its color, has a density of 5.02g/cm (cubed). Suppose you find a golden solid that has the mass of 25.04g and a volume of 4.99 cm (cubed). Have you found gold or iron pyrite?
Do the math
The density of red wine vinegar is 1.01g/cm (cubed), and the density of olive oil is 0.92g/cm (cubed). A salad dressing consisting of these two ingredients was left sitting too long. The ingredients separated in the bottle. Which ingredient is in which layer?
do the math
Water is unique because the density of its solid, ice, is less than the density of its liquid. Describe how life would be if this were not true.
