It is a guiz about physical properties and chemical properties.


Questions and Answers
  • 1. 

    What are signs of a chemical change?

    • A.

      Color change

    • B.

      Rust

    • C.

      Gas and light produced

    • D.

      All of the above

    Correct Answer
    D. All of the above
    Explanation
    The signs of a chemical change include color change, rust formation, and the production of gas and light. These are all indications that a chemical reaction has occurred. Color change can occur when substances combine or break apart, resulting in a different color. Rust formation is a chemical reaction between iron and oxygen, resulting in the formation of iron oxide. The production of gas and light can occur during various chemical reactions, such as combustion or decomposition. Therefore, all of the given options are signs of a chemical change.

    What is a sign of a physical change?

    • A.

      Split in half

    • B.

      Change in matter

    • C.

      All of the above

    • D.

      None

    Correct Answer
    C. All of the above
    Explanation
    All of the above options are signs of a physical change. Splitting something in half is a physical change because it alters the physical appearance of the object. Similarly, a change in matter, such as melting or freezing, is also a physical change as it involves a transformation in the physical properties of the substance. Therefore, all the given options indicate physical changes.

    Rate this question:

  • 3. 

    Is a chemical change a change in matter?

    • A.

      True

    • B.

      False

    Correct Answer
    B. False
    Explanation
    A chemical change refers to a process where one or more substances are transformed into different substances with new properties. It involves the breaking and forming of chemical bonds. On the other hand, a change in matter can include both physical and chemical changes. Physical changes do not involve the formation of new substances and only affect the physical properties of matter, such as size, shape, or state. Therefore, a chemical change is not the same as a change in matter, making the answer "False" correct.

    Rate this question:

  • 4. 

     A chemical change makes a new substance?

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    A chemical change refers to a process in which the composition and properties of a substance are altered, resulting in the formation of a new substance. This can involve the breaking and forming of chemical bonds, rearrangement of atoms, or changes in energy. Therefore, it is correct to say that a chemical change makes a new substance.

    Rate this question:

  • 5. 

    A phsical change does NOT change a substance.

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    A physical change refers to a change in the physical properties of a substance, such as its shape, size, or state of matter, without altering its chemical composition. In other words, the substance remains the same at the molecular level. Therefore, a physical change does not change the identity or composition of the substance, making the statement "A physical change does NOT change a substance" true.
