Which question can be used to identify a physical property of an element? Does a magnet attract the element?

Does rust form when the element is exposed to oxygen?

Do bubbles form when the element is mixed with an acid?

Does the element burn when held over a Bunsen burner flame?

Does a magnet attract the element?

Explanation:

This is because, the attraction of an element by a magnet is a purely physical property. It has to do with the orientation of the electrons in the element. It does not tell us of the composition of the element or how it reacts with other elements. Whereas, the other questions deal with the chemical properties of the element. That is, how it reacts with other elements or substances.

answer: option (4) is the correct answer.

explanation:

areas which are at low altitudes and near the equator tend to receive direct sunlight from the sun. hence, heat energy or radiations from the sun make these areas warmer and they have warmest water.

whereas areas which are at high altitudes and away from the equator do no receive direct sunlight. hence, no direct contact from the sun makes these regions colder and thus, they have colder water.

thus, we can conclude that the statement areas at low latitudes near the equator have the warmest water because they receive the most direct sunlight best explains the relationship between an area's geography and the temperature of its surface water.
