Question

Hydrogen bonds can be found between no other molecules except water.

Answer 1

Answer: Not really a question but....Two molecules of water can form a hydrogen bond between them that is to say oxygen-hydrogen bonding; the simplest case, when only two molecules are present, is called the water dimer and is often used as a model system.

Answer 2

Without hydrogen bonds, water molecules would move faster more rapidly, with less input of heat energy, causing the temperature to increase more for each calorie of heat added.

Explanation: This would also greatly reduce the amount of heat energy needed for phase changes from ice to liquid, and from liquid to vapor.
