# Matter: Properties

### Buoyancy, Viscosity, Density

Density Mass per unit volume
Viscosity a fluid's resistance to flow
Buoyancy an objects natural ability to float
Viscosity is.... sink
Fluids are either a Gas or Liquid
The mass of a rock is 24g, it's volume is 8mL. What is the density of the rock? 3g/mL
If a boat has a density of 1.6g/mL, will it float? No
If the buoyant force is greater than gravity will it sink or float? Float
What is Archimede's principle? The buoyant force of an object is equal the weight of the fluid displaced by the object.
volume the amount of space taken up by an object
A rock has a mass of 14g, and a density of 2.3g/mL. What is the volume of the rock? 6mL
In the equation D=m/v, v represents what value? Volume
A 20g object has a volume of 5mL, what is it's density? 4g/mL

A fluid with a high viscosity moves quickly or slowly? Slowly
A fluid with a low viscosity moves quickly or slowly? quickly
You can change the viscosity of a fluid by heating or cooling it

This property of matter has to do with the shape of the molecules. Viscosity
This property of matter has to do with the amount of "space" between the molecules. Density
You can change the density of the overall object by doing what? Changing it's shape
