Density Calculations
If the density of Material A is equal to 2.5 g/cm3 and the density of Material B is = to 1.0 g/cm3 which of them would be water?
What is Material B
The original block of Material A is cut into 10 equal pieces. When compared to the density of the original block, what will happen to the density of the original piece?
What is it will stay the same, density never changes.
What is the density of water?
What is water 1 g/cm3
What is the unit used for measuring density?
What is g/cm3 or g/ml
Is ice more dense than water? Explain how you know.
What is no, ice is less dense than water because it floats in water
A piece of wood has a density of 1.1 g/cm3 and a volume of 55 cm3; what is the wood's mass?
What is 60.5 grams
If a substance has a density of 9.5 g/cm3, it will do THIS when you put it in water
What is it will sink
What is the URL name of the website we performed the virtual density lab on? (no use of devices, phone or laptop!)
The Density lab and other Gizmos can be found at gizmos.explorelearning.com
What is the unit used for measuring mass?
What is grams or kilograms
How can you find the volume of an irregularly-shaped object? (What is the name of the process?)
What is water displacement
What would the volume be of a substance that has a density of 14 g/cm3 and a mass of 28 g?
What is 2 cm3 or 2 mL
Which has more volume: a kilogram of feathers or a kilogram of nails?
What is a kilogram of feathers
Is helium less dense than air? How do you know?
What is yes because a helium balloon rises in air
The formula for density is
What is mass divided by volume
In a density column, where does the most dense liquid go?
What is at the bottom
True or False: If an object sinks in water and you know its volume is 30 mL, its mass is 1 g.
What is false; its mass must be more than 30 g to have a density that is greater than 1 g/cm3
Which has more mass: a kilogram of nails or a kilogram of feathers?
What is they are the same, it's a trick question!
If you increase the mass of an object the volume increases, decreases, or stays the same?
What is increases?
A milliliter is always the same as 1 gram? T or F
What is false
When you heat a liquid up, what happens to the density?
What is it decreases, because it is transitioning to a gas
An unknown sample has a density of 6.0 g/cm3. If the sample was cut in half, what would be the density of each half?
What is 6.0 g/cm3
Which is more dense: a kilogram of feathers or a kilogram of nails
What is a kilogram of nails
If you heat an object, its density increases, decreases, or stays the same?
What is decreases?
What are the units for measuring volume?
What is milliliters or cubic cm (cm3)
In general, what phase of matter is most dense?
What are solids
