Pascal's Principle
The units of density for a solid
grams per centimeter cubed (must have cubed to be correct)
what is the volume of 20 g of a liquid with density equals 1g/ml
20 ml
What happens to water pressure as depth increases?
Increases
This is how you can predict whether an object will float or sink in a fluid
Density
The lift system is an example of this system
hydraulic systems
