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 |
| 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 |
| Find the density of a 45g object that's volume is 15mL. | 3g/mL |
| If a 10 mL object weighs 22 grams, whagt is its density? | 2.2g/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 |
| If you place Water with a density of 1.00g/mL in a beaker with corn syrup with a density of 1.360g/mL, which would be on the bottom? | Corn Syrup |
| Fluid A has a density of 2.3g/mL, Fluid B has a density of 0.78g/mL and Fluid C has a density of 1.27g/mL. Which fluid would be on the top in a density colum? | B |
| 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 |
