Question | Answer |
---|---|

What is the density of an object with a mass of 120g and a volume of 7mL? | 17.14g/mL |

What is the volume of 220g of an object with an density of 55g/cm3? | 4cm3 |

If you measure the volume of a regular object, the units will be what? | cm3 |

If you measure the volume of a liquid or an irregular object the unit will be what? | mL |

We have an object with a density of 610g/cm3, and a volume of 76cm3. What is the mass of the object? | 46,360g |

An object has a mass of 180 grams. it is 10cm in legnth, its height is 3cm and its width is 5cm. Will it float in water? | no |

What would be the unit used for volume if the density is 1.3g/mL | mL |

How do you measure the volume of a liquid? | graduated cylinder |

Density is defined as? | the ratio of mass to volume |

Viscosity is defined as? | a fluids resistance to flow |

Which is more viscus, honey or water? | honey |

If a fluid has a high viscosity then it flows? | slowly |

Buoyancy is defined as? | an objects natural ability to float. |

Buoyant force is defined as? | the upward force. |

How do you make and object too dense to float in water, float? | change it's shape |

An object with a density of 0.996g/mL will float or sink in water? | float |

What is the density of water? | 1g/mL |

When calculating density, mass is always measured in what units? | grams |

If a fluid has a high viscosity, then the density is high or low? | high |

How do you change the viscosity of a fluid without changing the composition? | heat or cool it. |
