    Electrical conductivity
  • What is the SI unit of mass?
    kilogram/kg
  • How does a parallax error occur?
    When the eye is not perpendicular to the measuring scale.
  • What property of materials is being described? The quantity of matter packed into a unit of the material.
    Density
  • Complete the sentence. Density is…
    The quantity of matter packed into a unit volume.
  • Name the instrument for measuring length shown in the picture.
    Vernier calipers
  • Why do we use SI units?
    To ensure that our measurements are fair and objective, to have common standards.
  • What is the name of the curved shape that the liquid level makes in narrow glass cylinders such as measuring cylinders?
    Meniscus
  • What are three important questions to ask before selecting a material to build an object?
    What purpose does the object serve? What physical properties does the object need to have? Is the cost of this material too much for the purpose?
  • What is volume?
    The amount of space an object occupies.
  • What is the instrument in the picture used for?
    Used to measure mass.
  • How can a parallax error be avoided?
    Bring your eye perpendicular to the measuring scale.
  • What property of materials is being described? Ability to withstand scratches.
    Hardness
  • Why do some objects float in water?
    Because they have a lower density that water.
  • Write the formula for finding the density of an object.
    Density = Mass / Volume
  • Complete the sentence. Length is defined as…
    The distance between two specific points.
  • Why do we use displacement cans?
    To measure the volume of an irregular solid.
  • Name the piece of lab equipment shown.
    graduated cylinder, measuring cylinder
  • What property of materials is being described? Temperature at which it changes in state from a solid to a liquid.
    Melting point
  • What property of materials is being described? Temperature at which it changes in state from a liquid to a gas.
    Boiling point
  • What are physical properties?
    The qualities that can be detected using our five senses or a measuring device.
  • What is mass?
    The quantity of matter in a body.
  • What property of materials is being described? Ability to support a heavy load without breaking or tearing
    Strength
  • What is the hardest substance found on the Mohs Scale of hardness?
    Diamond
  • Why do some objects sink in water?
    Because some objects have a higher density than water.
