Hydrogen bonding between molecules
- Water has a bizarrely high specific heat (in general, it's the highest of all liquids) due to hydrogen bonding between molecules. The specific heat is the amount of heat needed to raise a gram of water by one degree Celsius.

Jun 6, 2018 · Water has a high specific heat, meaning it takes more energy to increase the temperature of water compared to other substances. This is why water is valuable to industries and in your car's radiator as a coolant.

Feb 26, 2015 · Many know the reason of water's high specific heat to be hydrogen bonding. Partially, it's related to that: In giving heat to water, some heat is "spent" on loosening the hydrogen bonds rather than increasing water's kinetic energy.
Water is one of the latter—it has a high specific heat capacity because it requires more energy to raise the temperature. Water has a specific heat capacity of 4182 J/kg°C.
Water has a very high specific heat capacity of 4184 J/(kg·K) at 20 °C (4182 J/(kg·K) at 25 °C) —the second-highest among all the heteroatomic species (after ammonia), as well as a high heat of vaporization (40.65 kJ/mol or 2257 kJ/kg at the normal boiling point), both of which are a result of the extensive hydrogen bonding between its ...
Water has the highest specific heat capacity of any liquid. Specific heat is defined as the amount of heat one gram of a substance must absorb or lose to change its temperature by one degree Celsius. For water, this amount is one calorie, or 4.184 Joules.
Nov 21, 2000 · Why does water have such a high specific heat capacity? The important word in that question is "specific". That means per unit of mass; the specific heat capacity would be the amount of energy that must be added to a unit mass to raise the temperature by one degree.
Water has a higher specific heat capacity because of the strength of the hydrogen bonds. It requires a significant of energy to separate these bonds. Sand is comprised of metals and pyroxene (silicates [molecules with a SiO4 anion] that commonly contain Ca, Fe, and/or Mg), which are comprised of weaker covalent bonds.
