# Questions tagged [liquid-state]

The liquid state of matter is characterized by short-ranged correlations, as opposed to the long-ranged correlations of crystals and the absence of correlations in an ideal gas. Use this tag for questions specifically concerning the thermodynamics and statistical-mechanics of liquids. For the dynamical and mechanical properties of liquids, use the "fluid-dynamics" and "fluid-statics" tags.

### Confusion in Derivation of Excess Pressure in a Cylindrical Drop

I have recently learnt about surface tension and have developed a list of key points to solve problems:- Surface tension acts on the surface where a surface is defined as the interface(flat or curved)...

### Why does the air pressure not increase when I shake a coke bottle?

I tried this experiment lately and this happened, I shook a coke bottle and its air pressure remained the same but the coke came squirting out when I opened the lid. How is this possible?

### Why is pair distribution function equal to the Boltzmann factor?

On my statistical physics book it is written that the probability of finding two molecules at distance $r$ is not influenced by the presence of the other molecules, and for this reason, without any ...

### What is the distribution on the speed of particles in a liquid? (analogous to the Maxwell-Boltzmann distribution)

I know, for gases, the distribution on the speed of particles is the Maxwell-Boltzmann distribution. What is the corresponding distribution for liquids (e.g. water)? You can assume that the liquid is ...

### What does a local maximum under 1 in a two-point correlation function mean?

Two-point correlation functions like the radial distribution function (real space) and the structure factor $S(q)$ (reciprocal space) give information about correlations in a (typically) fluid ...

### Does a metal evaporate as single atoms or as molecules?

If I had a liquid metal, like Al, and I begin heating it so it evaporates, would the evaporating Al be in the form of atoms or as molecules?

### Steam Produced by Induction Cookers

I had recently noticed that induction cookers produce much more steam than normal gas tops and when I set the setting in the induction cooker to 'steam' it produces ever more steam. I used the same ...

### Effect of the temperature dependence of $\Delta H_{vap}$ on the vapor pressure?

I am aware that the enthalpy of vaporization of a fluid ,$\Delta H_{vap}$ is temperature dependent since it must be equal to zero at the critical temperature of said fluid, $T_c$ (although this is ...

### Convection from rapidly evaporating liquid inside vacuum chamber?

If we have a liquid that is is being actively heated and is rapidly evaporating (let's say around 1g/s for Ag at 1500K) inside a vacuum chamber, can convection around the liquid/vapor interface occur ...

### Can you remove air bubbles from oil by heating it just like you do with water? Does oil even have dissolved air?

I have a flat bottle filled half with water and top half with oil. It has a impeller connected with motor which slowly swirls oil and water to create beautiful lava lamp like effect. However after ...

### Pump fluid down HPHT gas well - fluid remains at top

Working offshore on a High Pressure / High Temperature gas well. We pumped 120 barrels of organic solvent into the well. The gas density was 0.3kg/m3. The fluid was 0.8kg/m3 & a boiling point of ...

### Quantum description of water

It seems that we have quantum description of solid and gas, but there seem to be few quantum models of liquid, with the exception of Liquid Helium or perhaps Fermi Liquid. For solids, we often study ...

### On the dielectric constants of liquid and vapor phases of a material

I can find the static dielectric constant of materials on the website or in a handbook. But for some liquids, it only shows the dielectric constant at the saturation vapor pressure. I am confused that ...
