Matter: Properties
Buoyancy, Viscosity, Density
Question | Answer |
---|---|
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 |
