Properties Of Water Labs Quiz - Quiz


Questions and Answers
  • 1. 

    Water is composed of what two elements?

    • A.

      Oxygen and nitrogen

    • B.

      Hydrogen and electrons

    • C.

      Protons and neutrons

    • D.

      Oxygen and hydrogen

    Correct Answer
    D. Oxygen and hydrogen
    Explanation
    Water is composed of oxygen and hydrogen. This is because water is a compound made up of two hydrogen atoms bonded to one oxygen atom. The chemical formula for water is H2O, indicating that there are two hydrogen atoms and one oxygen atom in each water molecule. Oxygen and hydrogen are the elements that make up water, and their combination creates the unique properties and characteristics of this essential substance.

    Water falling from the sky in the form of a rain drop because of what?

    • A.

      Adhesion

    • B.

      Cohesion

    • C.

      Surface tension

    • D.

      Polarity

    Correct Answer
    B. Cohesion
    Explanation
    Cohesion refers to the attraction between molecules of the same substance. In the case of water, the cohesive forces between water molecules are strong, causing them to stick together. This allows water to form droplets and fall from the sky as rain. The cohesive forces overcome gravity, enabling the water droplets to maintain their shape and size as they descend. Therefore, cohesion is the reason for water falling from the sky in the form of raindrops.

    Water is transported in plant tissues against gravity due to which of the following properties?

    • A.

      Polarity

    • B.

      Specific heat

    • C.

      Capillary action

    • D.

      Surface tension

    Correct Answer
    C. Capillary action
    Explanation
    Water is transported in plant tissues against gravity due to capillary action. Capillary action is the ability of a liquid to flow in narrow spaces without the assistance of external forces like gravity. This is possible because of the cohesive forces between water molecules, which allow them to "stick" together and move upwards through narrow tubes or spaces, such as the xylem vessels in plants. This property enables water to move from the roots to the leaves of a plant, providing essential nutrients and moisture for its survival.

    The ocean takes more energy to heat up and therefore longer to heat up than the sand.  Which property does this illustrate?

    • A.

      Adhesion

    • B.

      Cohesion

    • C.

      Specific heat

    • D.

      Surface tension

    Correct Answer
    C. Specific heat
    Explanation
    The given correct answer, specific heat, explains that the ocean takes more energy to heat up and a longer time compared to the sand. Specific heat refers to the amount of heat energy required to raise the temperature of a substance by a certain amount. Since water has a high specific heat, it can absorb and retain more heat energy before its temperature increases. This property makes it take longer for the ocean to heat up compared to the sand, which has a lower specific heat.

    A bug is able to walk on water due to water's ____.

    • A.

      Specific heat

    • B.

      Surface tension

    • C.

      Capillary action

    • D.

      Polarity

    Correct Answer
    B. Surface tension
    Explanation
    Surface tension is the property of a liquid that allows it to resist external forces and form a "skin" on its surface. This skin-like surface tension is created by the cohesive forces between the water molecules. When a bug walks on water, it is able to distribute its weight over a larger area, effectively breaking the surface tension and allowing it to stay afloat. Therefore, surface tension is the reason why bugs are able to walk on water.
