Liquid Definition and 990 Threads

Using the now-complete Cassini data set, astronomers have created a new global topographic map of Saturn's moon Titan that has opened new windows into understanding its liquid flows and terrain. https://www.sciencedaily.com/releases/2018/01/180106190439.htm I found this fascinating I hope others do.

Is liquid neon popular for bubble chamber detectors?

I'm working on a thought experiment. I want to know how much of the kinetic energy from a liquid mercury piston will be converted into work done on the hydrogen plasma in the form of compression, and how much work will be done on the piston in the form of compression. Note: assume piston walls...

What is the difference between aqueous solution and liquid solution? Note:I am a high school student and English is my second language. Thanks in advance!

When we fill a dewar or any other container with liquid argon (or liquid nitrogen), if I am correct, it sizzles because it is boiling. However, after we leave it inside for a few minutes, it stops. Does this happen because when you first pour it inside, the environment is of the liquid is much...

In the normal conditions (sea level) water evaporates at 100 C. In thermodynamics, we say: the amount of energy Q, can raise temperature of the liquid by the formula Q1=cm(t2-t1); when the liquid reaches the boiling point (100 C), we write Q2=Lm. Q2 is entirely spent on changing liquid state...

It will be very helpful if someone suggest any articles or reading materials on this topic for detailed study.

NASA announced in 2015 that they found some evidence for the existence of liquid water on Mars today - at least temporarily and underground. A new study comes to a different conclusion and proposes sand as origin of the observed material transport downhill. As interesting as these features...

Water vapor exists at a higher energy state than liquid water...but does that make a difference in the absorption bands? In other words, are the absorption bands of vapor and liquid water identical? Thanks!

Managed to get through a Ph.D. in nuclear physics without covering nuclear matter calculations (or I just don't recall it). My question is does nuclear matter have any shear strength, or is it like an ideal gas? What little I see of elementary calculations it's like a fermi gas so one would...

I am confused about the pressure depending only on the depth of the liquid, particularly for a cone. Up until P=mg/A=ρVg/A I understand it, but the problem I have is cancelling the area with the volume to give the height. How does this work when the volume of the liquid in the cone is not given...
