Out of all given options, determining if a rock is magnetic is an example of investigating an intensive property
Answer: Option C
<u>Explanation:</u>
Every element or compound consists of its unique physical and chemical properties. And these physical properties of the elements can be further classified as intensive and extensive physical properties. The intensive physical properties are the one which did not have any influence with the mass or amount of the element or compound. While the extensive properties will vary depending upon the amount and mass of the compound.
Thus, in this case, among the options given the investigations like weighing of sand, length of wire and recording volume of water will vary depending upon the size and amount of the inspecting substance. But the investigation of determining the magnetic nature of rock does not depend on the amount or size of the investigating substance.

First of all, As is a metalloid, not a nonmetal. Second of all, as the rows get higher on the periodic table, the elements are more reactive. As you move right on the periodic table, the elements become more reactive.
<span>An element is a pure substance that cannot be broken down by further chemical techniques. Therefore you could try heating, cooling, electrolysis or other methods to see if it was an element or a compound.</span>
