  • Question 3
    120 seconds
    Q.

    When water and other liquids stick together to form drops or thin films called ________________.

    answer choices

    adhesion

    capillary action

    cohesion

    surface tension

  • Question 4
    120 seconds
    Q. molecule in which opposite ends have opposite electric charges
    answer choices
    cohesion
    polar molecule
    hydrogen bond
    solution
  • Question 5
    120 seconds
    Q. Why does ice float?
    answer choices
    As water freezes, it expands and its density decreases.
    As water freezes, it takes up more hydrogen from the atmosphere, causing it to have a greater buoyancy.
    As water freezes, air becomes trapped between the hydrogen bonds of water molecules.
    As water freezes, it takes up more oxygen from the atmosphere, causing it to have a greater buoyancy.
  • Question 6
    30 seconds
    Q. The reason the water balloon did NOT pop while held over a flame is water's _________.
    answer choices
    Less dense than air.
    Hydrogen bonds between water molecules.
    polarity.
    high specific heat capacity.
  • Question 7
    30 seconds
    Q. Water is a universal solvent because it...
    answer choices
    It can be found anywhere
    It freezes when it gets cold
    floats when frozen
    Dissolves most substances
  • Question 8
    30 seconds
    Q. The fact that ice floats on liquid water is due to the fact that water's solid is ___________ than it's liquid form
    answer choices
    less polar
    more polar
    less dense
    more dense
  • Question 9
    30 seconds
    Q. Water striders can walk across the surface of calm water. Their feet push the surface of the water down slightly, but they do not break the surface. Why?
    answer choices
    The insects are light enough so they do not break the hydrogen bonds holding the water molecules together
    The insects actually use their wings to hover slightly above the water’s surface and they only skim it with their feet.
    The insect’s feet are non-polar, so they are repelled by the polar water molecules and are pushed away from the water’s surface.
    The insects are small enough to see the individual water molecules, so they are able to step carefully from one molecule to the next
  • Question 10
    30 seconds
    Q. A general definition of cohesion is the attraction of:
    answer choices
    particles of the same substance
    particles of a different substance
    particles of both the same and different substances
    particles of neither the same or different substances
  • Question 11
    30 seconds
    Q. Which term refers to water having partial positive and a partial negative charge?
    answer choices
    cohesion
    surface tension
    polarity
    adhesion
  • Question 12
    300 seconds
    Q. A high specific heat means...
    answer choices
    It heats up quickly with energy added
    It requires more energy to change temperature
