Relation between liquid water pressure and it's molecular dynamics

In summary, Alexandre is looking for literature on the relationship between liquid water pressure and its quantum molecular dynamics. They are seeking resources to better understand how pressure affects collisions and vibrations in water. Suggestions include looking at research compiled by Martin Chapin at the London South Bank University and considering water pressures as effects of molecular activities.

Hello everyone.

I'm am looking for some literature (articles or books) containing information about how is the relation between the liquid water pressure (macroscopic thermodynamic quantity) and it's quantum molecular dynamics (collisions, vibrations, etc.). Like: The pressure increase changes the collisions/vibrations/something this way...
I'am know very little about the subject so I don't know where to search...

You might start with the many papers and excellent bibliography compiled by Martin Chapin at the London South Bank University. http://www.lsbu.ac.uk/water/

It might also help if you view water pressures as effects of molecular activities, rather than causes.
 

1. What is the relationship between liquid water pressure and its molecular dynamics?

The pressure of a liquid is directly related to the molecular dynamics of its constituent molecules. This means that as the pressure of a liquid increases, the motion and interactions of its molecules also increase.

2. How does the molecular structure of water affect its pressure?

The unique molecular structure of water, with its polar covalent bonds and bent shape, allows for strong hydrogen bonding between molecules. This results in a higher pressure for water compared to other liquids with similar molecular weights.

3. Can changes in temperature affect the pressure of liquid water?

Yes, changes in temperature can affect the pressure of liquid water. As temperature increases, the molecules of water gain energy and move more rapidly, resulting in a higher pressure. Conversely, a decrease in temperature leads to a decrease in pressure.

4. How do intermolecular forces play a role in the pressure of liquid water?

The intermolecular forces between water molecules, such as hydrogen bonding, directly contribute to the pressure of liquid water. These forces create a cohesive network that resists compression, resulting in a higher pressure.

5. Is there a specific equation that relates liquid water pressure to its molecular dynamics?

Yes, there is an equation known as the Van der Waals equation that takes into account the molecular dynamics and intermolecular forces of a liquid, including water, to calculate its pressure at a given temperature and volume.
