Density
What is the definition of density?
What is the mass of an object per unit volume.
What is mass? The definition
Answer: The amount of matter in an object or substance.
What is volume? (definition)
Answer: The amount of space an object or substance occupies.
What is a Triple Beam Balance? What is it used for?
Answer: A mechanical instrument used to measure the mass of an object.
If the water level in a graduated cylinder rises from 20 mL to 30 mL after submerging an object, what is the volume of the object?
10 ML
What is the formula for calculating density?
Density = Mass / Volume.
How is mass measured? The units of measurement
Answer: In grams (g), kilograms (kg), or milligrams (mg).
What units are used to measure volume?
Answer: Cubic centimeters (cm³), liters (L), or milliliters (mL).
What are the parts of a Triple Beam Balance?
Answer: Main Beam, Beam Sliders, Zero Adjustment, and Pan.
What is the first step in the volume displacement method?
Answer: Fill a graduated cylinder with a known volume of water.
If an object has a mass of 60 grams and a volume of 15 cm³, what is its density?
Answer: 4 g/cm³.
Give an example of an object that would have a high mass
Answers will vary has to be reasonable
How is the volume of a liquid commonly measured?
Answer: In a graduated cylinder or beaker.
Why is it important to zero the balance before use?
Answer: To ensure accurate measurements.
How do you calculate the volume of an object using the displacement method?
Answer: The volume is the difference between the initial and final water levels.
Calculate the density of an object that weighs 80 grams and occupies a volume of 20 cm³.
Answer: 4 g/cm³.
Give an example of an object (solid) that would have a low mass
answers will vary (has to be reasonable)
What is the volume of an object that has a length of 4 cm, width of 3 cm, and height of 2 cm?
Answer: 24 cm³.
In what order do we move the sliders on the scale?
Greatest to least, 100s to 10s to 1s
What is a key advantage of using the volume displacement method?
Answer: It allows for measuring the volume of irregularly shaped objects.
What instrument would you use to measure mass accurately?
Answer: A Triple Beam Balance.
What instrument is used to calculate mass?
Triple beam balance
What is the volume of an object with a height of 12 inches, a width of 2 inches, and a length of 4 inches?
96 inches cubed
How can you determine the mass of an object using a Triple Beam Balance?
Answer: Add the values of the weights when the balance is zeroed.
What is the volume displacement method?
Answer: A method to measure the volume of an irregular object by submerging it in a liquid and measuring the amount of liquid displaced.
