  • 2. 

    A physical change will:

    • Create a new substance.

    • Will have an energy transference.

    • Will use oxidation.

    • Will change the properties of the substance.

    Correct Answer
    A. Will have an energy transference.
    Explanation
    A physical change refers to a change in the form or state of matter without altering its chemical composition. In this case, the correct answer is "will have an energy transference." This is because during a physical change, energy is either absorbed or released, resulting in a transfer of energy. This can be observed, for example, when ice melts into water or when a solid is heated and turns into a gas. The change in energy is a characteristic of physical changes and is not directly related to the creation of a new substance, oxidation, or changing the properties of the substance.

  • 3. 

    Three substances that sublimate are: dry ice (solid carbon dioxide), __________, and naphthalene.

    Correct Answer
    iodine, Iodine
    Explanation
    Sublimation is the process where a substance transitions directly from a solid to a gas without passing through the liquid phase. Dry ice (solid CO2), iodine, and naphthalene (commonly found in mothballs) are well-known examples of substances that undergo sublimation under certain conditions.

    Rate this question:

  • 4. 

    A chemical change will:

    • Will not have an energy transference.

    • Might use electrolysis.

    • Will create a new substance.

    • Will create a new compound.

    Correct Answer
    A. Might use electrolysis.
    Explanation
    A chemical change refers to a process where one or more substances are transformed into different substances with different properties. Electrolysis is a method that involves the use of an electric current to drive a non-spontaneous chemical reaction. It is commonly used to break down compounds into their constituent elements or ions. Therefore, it is possible for a chemical change to involve the use of electrolysis as a means to create new substances or compounds.

    Rate this question:

  • 5. 

    Explain, with an example, why matter cannot be destroyed.

  • 6. 

    Give an example of an exothermic energy transference and EXPLAIN why it is exothermic.

  • 7. 

    Give an example of an endothermic energy transference and EXPLAIN why it is endothermic.
