    Which of the following will be attracted to the magnet:  

    • Eraser

    • Paper clips

    • Pencil

    Correct Answer
    A. Paper clips
    Explanation
    Paper clips will be attracted to the magnet because they are made of iron or steel, which are magnetic materials. When a magnetic field is present, these materials become magnetized and are attracted to the magnet. Erasers and pencils are typically made of non-magnetic materials such as rubber or wood, so they will not be attracted to the magnet.

    The illustration that represents the liquid state of matter is:

    • Option 1

    • Option 2

    • Option 3

    Correct Answer
    A. Option 3
    Explanation
    Option 3 represents the liquid state of matter because it shows particles that are close together but still able to move and flow freely. This is a characteristic of liquids, where the particles have more energy than in a solid state but less energy than in a gas state. Option 1 and Option 2 do not accurately represent the liquid state as they either show particles that are too closely packed together (solid state) or too spread out (gas state).

    The characteristic of an object that has mass and takes up space is:                                 

    • A- volume

    •  B- mass

    • C- weight

    Correct Answer
    A. A- volume
    Explanation
    Volume is the characteristic of an object that refers to the amount of space it occupies. It is a physical property that is independent of the object's mass or weight. The volume of an object can be measured by determining the amount of space it displaces or by using mathematical formulas for different shapes. Therefore, volume is the correct answer to the question as it accurately describes the characteristic of an object that has mass and takes up space.

    “Boiling egg” is a process that changes the egg from liquid to solid. This            change is :

    • A-melting 

    • B- chemical change

    • C- physical change

    Correct Answer
    A. B- chemical change
    Explanation
    Boiling an egg involves a chemical change because the heat causes the proteins in the egg to denature and coagulate, resulting in the formation of a solid structure. This is different from a physical change where the substance retains its chemical composition but undergoes a change in state or form. In this case, the egg undergoes a chemical transformation as its molecular structure is altered during the boiling process.
