Variation of liquid density with temperature

AI Thread Summary
The discussion centers on determining the density of avgas 100LL at lower temperatures, starting from a known density of 725 kg/m^3 at 15°C. It is noted that density changes with temperature are generally small, but specific data can vary based on the substance's chemistry. While the original poster struggled to find detailed information online, they were directed to a useful resource that provided the needed data. The conversation highlights the importance of consulting specialized tables for commercial substances like avgas. Overall, the thread emphasizes the challenge of finding precise density values for specific temperatures.

I am looking for information on the density of a liquid at lower temperatures. I have it at 15C as 725 kg/m^3. The fluid is avgas 100LL.

I wish to determine it at lower temperatures. I believe that the change in liquid densitiess is rather small for temperature changes, but I can't verify this.

Any help is appreciated.

There isn't a general physical law - it depends on the chemistry of the substance.
If avgas is a standard commercial substance (sort of aviation fuel?) then there wil be detailed tables for it.
Have you tried google?
 
Yes I have without any luck, in addition to wikipedia and other sources. I just found this forum and thought that I would give it a try.

nucleus, thanks for the link. This is what I needed. I appreciate the information.

Thread 'Thermo Hydrodynamic Effect'

Vídeo: The footage was filmed in real time. The rotor takes advantage of the thermal agitation of the water. The agitation is uniform, so the resultant is zero. When the aluminum cylinders containing frozen water are immersed in the water, about 30% of their surface is in contact with the water, and the rest is thermally insulated by styrofoam. This creates an imbalance in the agitation: the cold side of the water "shrinks," so that the hot side pushes the cylinders toward the cold...
