What Happens to Two Water Molecules After They Come Together

question 80

Multiple Choice

What happens to two water molecules after they come together to form a hydrogen bond-do they vibrate more rapidly or less rapidly?

• A)Since the bonding of the two water molecules results in a loss of kinetic energy, the molecules would vibrate less rapidly.
• B)Since the bonding of the two water molecules results in an increase of kinetic energy, the molecules would vibrate more rapidly.
• C)Since the bonding of the two water molecules results in no change in kinetic energy, the vibration of the molecules does not change.
• D)The formation of the hydrogen bond stabilizes both molecules. The vibration rate is therefore less rapid.
