Which of the following describes the changes in forces of attraction that occur as H20 changes phase from a liquid to a vapor?

Options are;

(A) H-O bonds break as H-H and O-O bonds form.

(B) Hydrogen bonds between H2O molecules are broken.

(C) Covalent bonds between H2O molecules are broken.

(D) Ionic bonds between H+ ions and OH− ions are broken.

(E) Covalent bonds between H+ ions and H2O molecules become more effective.

B: Hydrogen bonds between H2O molecules are broken.

Explanation:

When water is changing from liquid form to vapour form, it's molecules move at a faster rate. This is because the bonds between the molecules have been broken as a result of the heat that converts the liquid to vapour.

And the type of bond that forms water molecules is hydrogen bonds.

Thus, hydrogen bonds are broken when converting from liquid to vapour phase.

explanation:

answer : one can design an experiment using a liquid and an additive that can be added to the liquid and observe the chemical changes in the reaction species.

one would need a beaker which is filled with a known amount of the liquid in which thermometer is placed to measure the temperature changes; after addition of the additive to the liquid solution one can note down the temperature change and find whether the reaction is endothermic or exothermic in nature. by subtracting the initial temperature value with the final temperature one can find the temperature changes.

various combinations of liquid and additive can be used. liquid in this case can be a known quantity of water and additives can be epsom salt or without epsom salt the experiment can be conducted to notice the changes. water and ice, hydrogen peroxide and dry yeast, vinegar and baking soda,etc.
