This is how volume is calculated.
What is Length x Width x Height? (#6)
100
A piece of wood that measures 4.0 cm by 8.0 cm by 6.0 cm has a mass of 100.0 grams. This is the volume of that piece of wood.
What is 192.0 cubic cm? (#11a) 4.0cm x 8.0cm x 6.0cm = 192.0 cm3
100
A piece of wood that measures 4.0 cm by 8.0 cm by 6.0 cm has a mass of 100.0 grams. This is the density of that piece of wood.
What is 0.5 (or 0.52) grams per cubic centimeter? (#11b) To solve: 1) Calculate volume. 2) Plug that into our density formula.
100
This is the amount of space something occupies.
What is volume? (#2)
100
This is the difference between 47mL and 47.0mL.
What is accuracy or precision? 47.0mL is more precise. (#14)
200
This is the formula for calculating density.
What is Density = Mass/Volume? (#7)
200
Given the information on our study guide, this is the density of corn syrup.
What is 1.4 (or 1.38) g/mL? (#10a) 27.6g/20mL = 1.38g/mL = 1.4 g/mL
200
The volume of a solution was measured in a graduated cylinder (45.0mL). If the mass of the solution is measured to be 70.75 grams, this is the density of the solution.
What is 1.6 (or 1.57) grams per milliliter? (#15) To solve: Plug mass and volume into the density formula.
200
This is the amount of matter in an object.
What is mass? (#1)
200
This is the characteristic of an astronaut's lucky horseshoe which would change when taken to the moon.
What is weight? (#12)
300
These are the four steps in calculating volume using Archimedes' Principle.
What are: 1) Take an initial (before) reading 2) Add the item 3) Take a final (after) reading 4) Subtract the initial from the final? (#20)
300
Given the information on our study guide, this is the density of vegetable oil.
What is 0.9 g/mL (or 0.92 g/mL)? (#10c) 13.8g / 15 mL = 0.92g/mL = 0.9g/mL
300
A cup of gold colored metal beads was measured to have a mass 532.0 grams. The volume of the beads is 54.0 cm3. Given the following densities, this must be what these beads are made out of: Gold = 19.3 g/cm3 Molybdenum = 10.28 g/cm3 Bronze = 9.87 g/cm3 Copper = 8.86 g/cm3
What is bronze?! (# 13) To solve: Step 1) Calculate the density of the beads: Density = 532.0 g / 54.0 cm3 = 9.85 g/cm3 = 9.8 g/cm3 Step 2) Compare that to the density of the metals given: 9.8 is the density of bronze, so the beads must be made out of Bronze!
300
This is a method for collecting data that can include hearing, smelling, feeling, and/or tasting.
What is observation? (#17)
300
This is the first thing you should do if you accidentally break a test tube while conducting a lab.
What is notify the teacher? (#18)
400
This is the formula for calculating mass if given density and volume.
What is Mass = Density x Volume? (#8)
400
This is the order, from bottom to top, in which corn syrup, rubbing alcohol, vegetable oil, and water would settle if all put into the same beaker.
What is corn syrup, water, vegetable oil, and rubbing alcohol? (#10f) To solve: 1) calculate the density of each fluid 2) order them from highest to lowest (since the highest density would be at the bottom)
400
Of corn syrup, rubbing alcohol, vegetable oil, and water, this one has the greatest density.
What is corn syrup? (#10d) To solve: 1) Calculate the densities of the three liquids 2) Compare that to the density of water. If it's less dense than water, it will float in water.
400
This is the movement of an object or substance to a different location.
What is displacement? (#4)
400
This is the type of variable that a researcher cannot control.
What is an dependent variable? (#16) (Remember: it's dependent upon the results of the experiment)
500
This is the volume formula, if given density and mass.
What is Volume = Mass/Density? (#9)
500
If a substance has a density of 2.7 g/cm3, and a piece of that substance has a mass of 43 g, this is the volume of that piece.
What is 15.9 cubic cm? (#21)
500
Of corn syrup, rubbing alcohol, and vegetable oil, this/these would float in water.
What are rubbing alcohol and vegetable oil. (#10e) To solve: 1) Calculate the densities of the three liquids 2) Compare that to the density of water. If it's less dense than water, it will float in water.
500
... is equal to the weight of the liquid displaced by the object.
What is the buoyant force on an object? (#5)
