density quiz Flashcards
How do you find density?
Mass divided by volume
What is the density of water?
1 g cm3.
An object has an density of 0.9g/ml. Will it sink or float in water?
It will float because the density of water is greater than the object of 0.9.
How does the density of warm water compare to cold water?
Cold water has a greater density than warm water.
How does the density of saltwater compare to freshwater?
Saltwater has a greater density than freshwater.
if a substance has a greater density of 1ml, will it sink or float?
sink, because the density of water is 1.
Density measures…
…how tightly packed particles are in a substance.
The size of an object can change, but it’s density will remain constant.
True.
Mass
Total amount of matter or stuff in an object.
Weight
The force of gravity on an object.
weight = mass x gravity
density = mass/volume
How might you use density to intensify an unknown substance
L x W x H
