What is a quantitative physical property?
A physical property that uses number or amounts to describe the substance.
300
What is one appropriate unit for the volume of a solid?
cubic centimeters
300
What is density?
The amount of matter in a given volume or how smashed together particles of a substance are.

As an ice cube melts to a liquid and then eventually boils, what happens to the speed of the particles?
the speed of the particles increases
300
What are the relative charges of the subatomic particles?
protons are positive, neutrons are neutral, electrons are negative
400
What is a qualitative physical property?
A physical property that uses words to describe a substance.
400
What is the definition of volume?
the amount of space matter occupies
400
If a substance has a mass of 20 g and a volume of 4 milliliters, what is its density? WITH UNITS!
5 g/mL

As an ice cube melts to a liquid and eventually evaporates to a gas, what happens to the arrangement of the particles?
the particles spread out so there is more space between them
400

How can you determine whether a substance will float or sink in water? BE specific!!
If the substance has a density greater than the density of water, 1 g/mL, it will sink. If a substance has a density less than 1 g/mL it will float.
