Hydrogen bonds are strong, such as in water. Therefore it take more energy (heat) to bring it to a boiling point (break or weaken the bonds so they are more freely moving as in a gas). Therefore it has a larger heat capacity. The above answer, while mostly correct, is wrong in relating the boiling point of a material to its heat capacity. Heat capacity is a measure of how much energy it takes to increase a specific amount of a substance by 1 °C. It doesn't have anything to do with phase changes as implied by the answer above. The heat capacity of a substance is generally a function of the number of degrees of freedom of the molecule. Larger molecules have more degrees of freedom than do smaller molecules. Heat capacity has to do with how well molecules are able to store (or trap) energy. This can be in translational energy, molecular vibrations and molecular rotations for instance. Hydrogen bonds provide another way for energy to be stored. As heat is added to the substance, some of that energy goes into breaking the bonds rather than simply raising the temperature. The more places a molecule has to deposit energy (degrees of freedom), the higher the heat capacity. See the Wikipedia link to the left for more information.
What else can I help you with?
Most of waters unique properties result from the fact that water molecules?
Most of water's unique properties result from its ability to form hydrogen bonds with other water molecules. These bonds contribute to water's high surface tension, specific heat capacity, and thermal conductivity, as well as its role as a universal solvent.
What properties do hydrogen bonds give water?
* Cohesion * Adhesion * Capillary Action * High Specific Heat (resists temperature change) * Ability to dissolve most substances ("the solvent of life") * Evaporative cooling * Buoyancy of ice
What is released when water condenses as hydrogen bonds form?
Heat energy is released when water condenses as hydrogen bonds form. This is because the molecules are coming closer together, releasing energy that was used to keep them apart in the vapor phase.
Are hydrogen bonds easily broken?
Heat. Intermolecular Hydrogen bonds (between two water molecules) are broken as water is heated to boil.The intramolecular hydrogen bonds (between H and O) stay intact
Are hydrogen bonds strong?
The term hydrogen bonding refers to a weak interaction between two molecules that contain an H atom bonded to a very electronegative atom, such O, N, and F. Hydrogen bonding does not occur within molecules, but rather between to molecules.Of course, the atoms of hydrogen can also form regular covalent or ionic bonds with other atoms to form molecules, and so these are in some sense hydrogen bonds, but that's not usually what people mean when they say the term "hydrogen bond."See the Web Links for more information about hydrogen bonding.
Does covalent bonds give water a low heat capacity?
No, covalent bonds do not directly affect water's heat capacity. Water's high heat capacity is due to its hydrogen bonds, which allow for a large amount of heat to be absorbed or released without causing a large temperature change.
Do covalent bonds give water a low heat capacity?
No, covalent bonds do not directly contribute to water's high heat capacity. Water's high heat capacity is due to its ability to form hydrogen bonds, which allow it to absorb and release heat energy without changing temperature significantly. These hydrogen bonds are formed between water molecules, which have polar covalent bonds.

Why does water have a high and specific heat?
Water's high heat capacity is a property caused by hydrogen bonding among water molecules. When heat is absorbed, hydrogen bonds are broken and water molecules can move freely. When the temperature of water decreases, the hydrogen bonds are formed and release a considerable amount of energy.
Does water have hydrogen bonds?
Yes, water has hydrogen bonds. These bonds form between the hydrogen atoms of one water molecule and the oxygen atom of another water molecule. This gives water its unique properties such as high surface tension and specific heat capacity.
Why does water have a specific heat capacity?
Water has a high specific heat because of the hydrogen bonds acting on the molecules. These hygrogen bonds can "store" thermal energy, and this allows water to absorb or release a lot of heat without a large change in temperature.
Are solvent cohesive and temperature stabilization properties of water due to its hydrogen bonds?
Yes, the solvent cohesive and temperature stabilization properties of water are indeed due to its hydrogen bonds. The hydrogen bonds between water molecules give it a high surface tension, allowing it to stick to itself (cohesion) and other substances (adhesion). Additionally, the hydrogen bonds also contribute to water's high specific heat capacity, which helps to stabilize temperature by absorbing and releasing heat slowly.
Do covalent bonds give water low heat capacity?
Water has a relatively high heat capacity, not a low heat capacity. Heat capacity is the amount of heat energy required to raise the temperature of a substance by a certain amount. Water has a high heat capacity because it requires a lot of energy to raise its temperature. This property of water is due to the strong hydrogen bonds between its molecules, which require a lot of energy to break. As a result, water can absorb or release a large amount of heat without undergoing a significant change in temperature, making it an excellent heat sink. The specific heat capacity of water is the amount of energy required to raise the temperature of a substance by 1 degree Celsius (or 1 Kelvin). Water has a high specific heat capacity because it requires a lot of energy to raise its temperature. This property of water makes it an important factor in the regulation of temperature in living organisms and in the Earth's climate. It is also why water is often used as a coolant in various types of cooling systems, such as in car radiators and air conditioners.
What type of bond gives unique properties to water?
Hydrogen bonds give unique properties to water, such as high cohesion, high surface tension, and high specific heat capacity.
How hydrogen bonds affect the physical properties of water?
Hydrogen bonds between water molecules give water its high surface tension, cohesion, and thermal properties (high specific heat capacity and heat of vaporization). These properties allow water to play a crucial role in biological systems and the Earth's climate regulation.
What is most directly responsible for water's unique properties?
Water's unique properties are primarily due to its structure and hydrogen bonding. The polar covalent bonds between oxygen and hydrogen atoms cause water molecules to be attracted to each other, forming hydrogen bonds. These hydrogen bonds contribute to water's high surface tension, specific heat capacity, and ability to act as a universal solvent.
What molecules enables water to form drops and store heat?
The hydrogen bonds within H2O are very strong and the surface tension that allows for water droplets to form comes from the strong cohesion of water molecules to other water molecules. The high specific heat capacity is also due to the strength of the hydrogen bonds.
