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
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 density of water?
What is water 1 g/cm3
What is the unit used for measuring density?
What is g/cm3
How can you find the volume of an irregularly-shaped object? (What is the name of the process?)
What is water displacement (aka volume displacement, aka displacement method)
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
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 is a ratio of a substance's _____ to its _____
ratio of a substance's mass to its volume.
What is the base unit used for measuring mass?
What is grams
Is ice more dense than water? Explain how you know.
What is no, ice is less dense than water because it floats in water
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 up a gas, what happens to its density? Does its density increase, decrease, or stay the same?
What is decreases?
What are the BASE units for measuring volume?
What is liters or cubic m (m3)
In general, what phase of matter is most dense?
What are solids
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 what happens to the volume of the object? Does the volume increases, decreases, or stays the same?
What is increases?
How much water will a cube with a length of 1 cm displace?
What is 1 mL?
In a density column, where does the most dense liquid go?
What is at the bottom
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 (give an example)?
What is yes because a helium balloon rises in air
A milliliter is always the same as 1 gram? T or F
What is false
When you heat a liquid up, what happens to its volume? What happens to its density?
What is its volume increases. Because the volume increases its density would decrease.
(a liquid is transitioning to a gas)
