Gaseous vapor observed when handling dry ice (solid co_2 2 ) physical or chemical

Dry ice is frozen carbon dioxide. It is easy to assume that the fog surrounds dry ice is carbon dioxide returning to it's gaseous however, you can not see that process. The vapors you see is the water molecules in the air condensing as a result of the cooling or energy removal by the dry ice. When energy is removed from water molecules they become colder and move slower than water in a gaseous. Similar to clouds in the air, the water condenses into a form that you can see.

Option (C) is the correct answer.

Explanation:

Water is a polar molecule because it has two polar single bonds and also it has bent shape structure.

Since the oxygen atom of water has two lone pair of electrons and also dipole moment is more towards the oxygen atom. As a result, there will be increase in electron density across the oxygen atom which will induce a negative charge on oxygen and positive charge on hydrogen atom.

Thus, water molecule becomes polar in nature.
