Properties of Matter Notes

What is Matter?

• In your own words, write a definition for matter.

• Our definition for matter is:– Matter is anything that has stuff in it (mass) and

takes up space (volume)

Measurements of Matter

a. ______________ : The amount of matter in an object

a. Most common units used to measure _____________are milligrams, grams, & kilograms

b. Volume: _________________________________

a. Most common units used to measure volume are: __________, ______ & ___________

b. 1 mL = __ cm3 or cc (cubic centimeters)

The amount of space an object takes up

Milliliter Liter Centimeters cubed

Mass

Mass

1

c. ________: the amount of matter in an object per the amount of space the object takes up– Formula for density is: ______________

– Labeled as g/mL, kg/L, g/cc, or mg/cm3

– must have both mass and volume labels present

Density

D = Mass

Volume

How is Mass different than Weight

• As long as you are on Earth, there really NOT a difference

• However, there is a scientific difference– Mass is ______________________________BUT– Weight is _____________________________

the amount of matter in an object

the measure of amount of gravitational pull on an object

Practice

• If a box has a mass of 20 g and a volume of 10 cc, what is the density of the box?

D = 20 g 10 cc

D = 2 g/cc

More Practice

• If the volume of a rock is 250 mL and it has a mass of 125 g, what is its density?

D = 125 g 250 mL

D = 0.5 g/mL
