Question

Compared to many other liquids, water has a high heat of vaporization, which means a relatively large amount of heat must be added to the water before the water molecules are moving fast enough to escape the surface as a gas. Which of the following explains why water has a high heat of vaporization?

A Adding heat to the water causes the molecules to move around, and the motion keeps pushing them back below the waters surface

B As water molecules heat up they tend to form more hydrogen bonds with each other, making it difficult for any of the molecules to vaporize.

C Water molecules have a relatively high molecular weight compared to other molecules, so more energy is needed for the water molecules to vaporize.

D Enough heat must be added to water molecules' hydrogen bonds to break the bonds and provide the molecules enough energy to escape the surface..​

Answer 1

D

Step-by-step explanation:

Water has a fairly high specific heat, which means that enough heat must be added to it to break the hydrogen bonds between the molecules, allowing them to move freely from each other and escape the water's surface.
