What is the formula for Density?
D = M/P
100
What is the formula for mass?
M = D x V
100
Define volume
THe amount of space that an object has
100
What is the metric system?
The metric system is the units we use to measure in
100
Fill in the blanks: Comparing the density of an object to the density of water can tell you whether the object will _______ or _______
sink, float
200
What is the density of pure water?
1.0 g/cm3
200
What is mass?
How much matter is in something
200
How is the volume of a rectangular prism calculated?
Width x Length x Height
200
What is matter?
Matter is anything has mass and volume. Everything that you can touch, feel, see and taste
200
How is density related to the ability of an object to float?
If the density of an object exceeds (is bigger than) the density of water, it will sink. If the object has a density that is less than the density of water, it will float.
300
What is the density of an object with a mass of 45g and a volume of 8cm3
5.625 g/cm3
300
What tool is used to find mass and what is the measurement unit?
The tool is an electronic balance or a triple beam and it is measured in grams or kilograms
300
How are 1 mL and 1 cm3 related?
They are both measurements of volume
300
Define what gravity is.
Gravity is the force that attracts a body toward the center of the earth, or toward any other physical body having mass.
300
Name all of the units for density (volume, mass, density)
Volume = mL or cm3 Mass = g, kg Density = g/mL or g/cm3
400
What will happen if you drop an object into water that has a density of 1.33g/cm3?
It will sink
400
When two boxes have the same mass, do they have the same density? Why?
No because volume effects the density.
400
How is the volume of a cylinder measured?
3.14 R2 x H (Pie x Radius squared x height)
400
Explain what buoyancy is.
The tendency of an object to float
500
Name the 3 states of matter from highest to lowest density
Solid = the highest density Liquid = "medium" density Gas = the least density
500
Does your mass or weight change on other planets? Also explain what causes this to happen.
Your weight changes. This happens because weight is affected by gravity.
500
Explain the displacement method of finding the volume of an object.
When an object is irregular, you can find the volume using displacement. This is done by putting water in a graduated cylinder and recording the volume. Drop the object in the water and record the changed volume. Subtract the original volume from the final volume to determine the volume of the the object.
500
What does "standardize" mean?
To evaluate by comparing to a standard

Solve this problem: The mass of the basketball is 0.6 Kilograms. The volume of the basketball is 456 mL. What is the density of the basketball
M = 600 grams V= 456 mL D = 1.32 g/mL
