Question What causes a water molecule to be polar?

A. The Oxygen atom is larger and stronger than the Hydrogen atoms so the electrons spend more of their time nearer the hydrogen

B. The Oxygen atom is smaller and weaker than the Hydrogen atoms so the electrons spend more of their time nearer the oxygen

C. The Oxygen atom is smaller and weaker than the Hydrogen atoms so the electrons spend more of their time nearer the hydrogen

D. The Oxygen atom is larger and stronger than the Hydrogen atoms so the electrons spend more of their time nearer the oxygen

The correct option is D

Explanation:

Water molecules are polar because there structures are made up two sides; the positively charged side (the hydrogen side) and the negatively charged side (the oxygen side). The atoms in the water molecule are joined together by covalent bond - meaning there is sharing of electrons between the constituent atoms. The oxygen atom is bigger/larger (in size) and has a higher electronegativity (ability to attract electrons) hence, the electrons tend to spend more time around the oxygen than the hydrogen atom.

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.
