Water has stronger hydrogen bonds than Methane. More energy is required to break them, hence the difference in boiling point
When an egg is boiled, the proteins present inside the egg get denatured and coagulate. After boiling the egg, the water present in it is absorbed by the coagulated protein through H-bonding.
noWater is inorganic compound made up of H and O . Proteins are separate organic molecules
Water is made up of molecules with the formula H2O (two hydrogens attached to an oxygen) Of course the H (hydrogen) and O (oxygen) are atoms.
Normally you have a pressure of approx. 2 bar (2kPa) in a pressure cooker.At this pressure the boiling point of water is 120 0C (393 K) or 247 FSee the Related Questions to the left for more information about how pressure affects the boiling point of water.

You will find that it will separate into two ions:hydrogen (H+) and hydroxyl (OH-).

To separate H2O(liquid) into H2(gas) and O2(gas), you would use a process called electrolysis. This involves passing an electric current through the water, and collecting hydrogen as it forms as bubbles at the cathode (negative terminal), as well as collecting oxygen as bubbles at the anode (positive terminal). You will get half as much oxygen as hydrogen. For a more detailed description, see the Wikipedia page: http://en.wikipedia.org/wiki/Electrolysis_of_water you get H and O2 from H2O by using a method called Electrolyzation in which you separate O2 and H and this method is used in advanced submarines to have O2 from water.
Acids in water will (partially)split into ions: protons (H+) and anions (conjugate base ions.
Strong acids: if its a strong acid, it will separate completely in water, meaning that the H+ ion concentration in the water will increase, which in turn causes the pH to decrease example: HCl -> H+ + Cl- Weak acids: weak acids don't separate completely in water, but because they are acids, they still separate. You can figure out how much of the acid has broken up by using a rice table and looking up the Ka. example: HCN <--> H+ + CN-
Water's boiling point is very high for its size because of extensive network of H bonds.Freezing point is higher than expected because liquid water has only 15% more H-bonds than ice, making it easy to go from liquid to solid.Water has a high specific heat or heat capacity.Hydrogen bonds separate molecules as ice, making ice less dense than water, which means it floats
yes. it lowers its temperature. the NaCl is broken apart by the H2O so that the Ions (Na + Cl + H + H +O) are floating around. No new chemical compounds are formed because nothing is precipitated.
Both H2O and HF possess H bonds as their intermolecular force but H bonds of HF are stronger than that of H2o. therefore boiling point of than that of H2O. But experimental boiling point is high in H2O than that of Hf
Water has stronger hydrogen bonds than Methane. More energy is required to break them, hence the difference in boiling point
ive seen a few different equations but this one is the correct one, because ive researched it a lot. this is the chemical equation for boiling water H2O(1)-->H2O(g)delta(h)-->O
