100
Which state of matter usually sinks the best?
What is solids?
100
What determines whether an object will float or sink?
What is, whether the density of the object is higher or lower than the density of the liquid it's in.
100
The unit for volume of a liquid is _____.
What is mL?
200
Which block has the lowest density? Each block has the same volume.
What is gas? The particles are more spread out so there are fewer of them when compared to a solid or liquid.
200
Cork has a density of 0.24 g/cm3 and Styrofoam has a density of 0.005 g/cm3. Which material would float the best?
What is, Styrofoam would float the best because it has the lowest density. However, both materials would float on water since they each have a density that is lower than water.
200
The unit for density of a solid is ______.
g/cm3
300
Give an example of a solid that floats on water
What is wood or ice because they have a lower density than water?
300
I have to make a boat that can float with 10 g on top. The volume of my boat is 2 cm3 which makes my density 5 g/cm3. Because of its density, my boat doesn't float on water. What could I change to make sure my boat doesn't sink?
What is, increase the volume of the boat to lower the density?
300
What is the mass of a piece of cork that has a volume of 15 cm3 and a density of 0.24 g/cm3?
m = D x V
m = 0.24 g/cm3 x 15 cm3
m = 3.6 g
400
The liquid state of _____ is more dense than the solid state.
What is mercury?
400
We have equal amounts of water and seawater in our bucket at the beach. Water has a density of 1g/mL and seawater has a density of 1.03 g/mL. Which one will float on the other?
What is the water will float because it has a lower density?
400
I have a piece of gold that is 20 g and has a volume of 31 cm3. What is the density of this piece of gold?
D = m/v
D = 20 g/31 cm3
D = 0.65 g/cm3
500
____ is/are less dense than liquids.
What is gases?
500
Objects that have a ______ density than the liquid they are in will sink.
What is a higher density?
500
I am trying to find the volume of my coffee cup which is an irregular shape so I immerse it in a large measuring cup full of water. Before I insert the cup, the volume of water is 250 mL. After I insert the cup, the volume of water reads 500 mL. What is the volume of my coffee cup?
V = V2 - V1
V = 500 mL - 250 mL
V = 250 mL
