  • What is the name of the curved shape that the liquid level makes in narrow glass cylinders such as measuring cylinders?
    Meniscus
  • What property of materials is being described? A measure of how readily heat passes through it.
    Thermal conductivity
  • How can a parallax error be avoided?
    Bring your eye perpendicular to the measuring scale.
  • Why do some objects float in water?
    Because they have a lower density that water.
  • Why do some objects sink in water?
    Because some objects have a higher density than water.
  • What property of materials is being described? Ability to withstand scratches.
    Hardness
  • What property of materials is being described? Temperature at which it changes in state from a liquid to a gas.
    Boiling point
  • What property of materials is being described? A measure of how readily electricity passes through it.
    Electrical conductivity
  • 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
  • Name the instrument for measuring length shown in the picture.
    Vernier calipers
  • What is the hardest substance found on the Mohs Scale of hardness?
    Diamond
  • Why do we use SI units?
    To ensure that our measurements are fair and objective, to have common standards.

    The quantity of matter packed into a unit volume.
  • Complete the sentence. Length is defined as…
    The distance between two specific points.
  • What is the SI unit of mass?
    kilogram/kg
  • Name the piece of lab equipment shown.
    graduated cylinder, measuring cylinder
  • What is volume?
    The amount of space an object occupies.
  • 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? The quantity of matter packed into a unit of the material.
    Density
  • Why do we use displacement cans?
    To measure the volume of an irregular solid.
  • What are physical properties?
    The qualities that can be detected using our five senses or a measuring device.
  • How does a parallax error occur?
    When the eye is not perpendicular to the measuring scale.
  • What is the instrument in the picture used for?
    Used to measure mass.
  • 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 property of materials is being described? Bend without breaking.
    Flexibility
  • Write the formula for finding the density of an object.
    Density = Mass / Volume
