Questions and Answers
  • 1. 

    What is this piece of equipment?

    • A.

      Beaker

    • B.

      Erlenmeyer flask

    • C.

      Dropper

    • D.

      Option 4

    Correct Answer
    C. Dropper
    Explanation
    The correct answer is dropper because a dropper is a piece of equipment used in laboratories to transfer small amounts of liquid. It consists of a glass tube with a rubber bulb at one end, allowing for precise and controlled dispensing of liquids. A beaker and Erlenmeyer flask are both types of glassware used for holding and measuring larger volumes of liquid, while option 4 is not specified and therefore cannot be determined as the correct answer.

    What is this?

    • A.

      Beaker

    • B.

      Erlenmeyer flask

    • C.

      Graduated cylinder

    Correct Answer
    A. Beaker
    Explanation
    The correct answer is "beaker" because a beaker is a cylindrical container with a flat bottom and a pouring lip, commonly used in laboratories for holding, mixing, and heating liquids. The other options, Erlenmeyer flask and graduated cylinder, are different types of laboratory glassware with distinct shapes and purposes.

    • C.

      Balance

    Correct Answer
    C. Balance
    Explanation
    The given options are test tube, test tube rack, and balance. A test tube is a small cylindrical container used for holding and mixing small quantities of liquid substances. A test tube rack is a tool used to hold multiple test tubes upright and organized. A balance is a device used to measure the mass of an object by comparing it to known masses. Out of the given options, a balance is the only one that is used for measuring mass, making it the correct answer.

      Funnel

    • C.

      Test tube

    Correct Answer
    B. Funnel
    Explanation
    This is a funnel, which is a cone-shaped utensil with a narrow tube at the bottom used for pouring liquids or other substances into a container with a small opening. It is commonly used in cooking and laboratory settings to transfer liquids without spillage or contamination. The other options, a round flask and a test tube, are different types of glassware used for holding and storing liquids in scientific experiments.

      Erlenmeyer flasks

    • B.

      Beakers

    • C.

      Test tubes

    Correct Answer
    C. Test tubes
    Explanation
    These are different types of laboratory glassware commonly used in scientific experiments. Erlenmeyer flasks are conical-shaped flasks with a narrow neck, used for mixing and heating liquids. Beakers are cylindrical containers with a flat bottom and a spout, used for holding and measuring liquids. Test tubes are small cylindrical tubes with a rounded bottom, used for holding and mixing small amounts of liquids or conducting chemical reactions.
