The H2O molecules without attaching another H2O molecules is smaller and body is easier to absorb H2O through cell member, but H2O molecules usually stick together and become a larger molecules. Not true. They "stick together" only when their energy is taken removed, as in the form of ice. That sticking together effect you're referring to are the hydrogen bonds that exist between individual molecules. When water is boiling, the energy from the stove is absorbed by the water, breaking the hydrogen bonds, so it goes from being water to steam.

If I want to make water with weaker hydrogen bonds between molecules (H2O) for daily drinking purpose, what can I do to weaker hydrogen bonds?
On the other words, if water is a large chain of molecules with stronger hydrogen bonds, how can I break this large chain into small chain? so small (H2O) molecules can get into cell member easily.
A larger group of H2O molecules : (H2O)(H2O)(H2O)(H2O)(H2O)(H2O)(H2O) A smaller group of H2O molecules : (H2O) (H2O) (H2O)
Do you have any suggestions? Thank you very much for any suggestions (^v^)

f I want to make water with weaker hydrogen bonds between molecules (H2O) for daily drinking purpose, what can I do to weaker hydrogen bonds? @ 100 degrees Celsius, the hydrogen bonds break. They do not break before than, unless a chemical is added and it disrupts the equilibrium. Essentially, only heat breaks them, nothing else unless something is added to change the chemistry

If I add little bit salt into water, how do salt change the chemical equilibrium among hydrogen bonds?
Furthermore, once 100 degrees Celsius is reached, when water cools down into room temperature, would weak hydrogen bonds between (H2O) molecule be maintained without adding any elements to change the chemical equilibrium?
Do you have any suggestions? Thank you very much for any suggestions (^v^)

If energy is removed from steam, the molecules slow down, and hydrogen bonds begin to form, producing liquid water.
When salt is added, it shifts the boiling point up, so rather than boiling at 100, it boils at a higher temperature. Here's an explanation I found online, I think it's quite good:
The boiling point of any liquid is defined as the temperature at which the vapour pressure of the liquid becomes equal to the atmospheric pressure.
When salt is added to water, sodium chloride dissociates into sodium and chlorine ions. These charged particles alter the intermolecular forces between water molecules. In addition to affecting the hydrogen bonding between water molecules, there is an ion-dipole interaction to consider.
Water is a polar molecule and hence has a dipole, which means one side (the oxygen side) is more negative and the other side (the hydrogen side) is more positive. The positively-charged sodium ions align with the oxygen side of a water molecule, while the negatively charged chlorine ions align with the hydrogen side of a water molecule. The ion-dipole interaction is stronger than the hydrogen bonding between the water molecules, so more energy is needed to move water away from the ions and into the vapour phase.
Even without a charged solute, adding particles to water raises the boiling point because part of the pressure the solution exerts on the atmosphere now comes from solute particles, not just solvent (water) molecules. The water molecules need more energy to produce enough pressure to escape the boundary of the liquid. The more salt (or any solute) added to water, the more raised is the boiling point. The phenomenon depends on the number of particles formed in the solution. Hence, it is called a colligative property.
The temperature needs to be increased about a one-half degree Celsius for every 58 grams of dissolved salt per kilogram of water.

Correct... The interaction between water and the salt is stronger, so more energy is required to break that ionic bond formed.
The molecular size of a water molecule will never decrease. If you want to separate them, you heat up the water until it turns to steam. That's the furthest apart they will be.

Someone from YouTube mention about adding little bit salt into water, body would be more easy to absorb water through cell membrane, they also mention that smaller (H2O) molecules would be easy to pass through cell membrane, it seems that adding salt into water is making (H2O) molecule larger instead of smaller, could it be correct? In practice, if I want to make (H2O) molecules separate farther, not smaller molecules, so each individual (H2O) molecules would get farther to pass through cell membrane, is there any trick to do so? Do you have any suggestions? Thank you very much for any suggestions (^v^)

None of that is correct. Salt (for example, NaCl) and water do form a bond, but they're temporary and insignificant. The chemical reaction is: NaCl (solid) + H2O > Na+(aqueous) + Cl-(aqueous) + H2O When added to water, the Na+ section of NaCl is attracted to the oxygen side of the water molecules, while the Cl- side is attracted to the hydrogens' side of the water molecule. ![](https://qph.fs.quoracdn.net/main-qimg-8739d3c7496e7dacb2cca06a3f56cff6-c) This causes the sodium chloride to split in water, and the NaCl dissolves into separate Na+ and Cl- atoms. A hydration shell is formed around them which prevents Na+ and Cl- to form ionic bonds.
