Absolute Derivation

AI Thread Summary

The discussion centers on the Absolute Scale of Temperature as presented in SL Arora's Class 11 textbook. It highlights that this concept is essentially an application of Charles's Law, where the volume-to-temperature ratio remains constant at constant pressure. The temperature is expressed in degrees Celsius, necessitating the addition of 273.15 to convert to the absolute scale. This clarification helps in understanding the relationship between temperature and volume in gases. Overall, the connection between Charles's Law and the Absolute Scale of Temperature is emphasized.

TL;DR Summary: I can't figure out the derivation of this formula.

It is from [ Class 11th] SL Arora, pg no. 11.3, the heading is [11.7] Absolute Scale of Temperature.

This is just Charles law (V/T is onstant at constant pressure), with T expressed in degrees Celsius, so you get (T+273.15) in the expression, instead of t

Oh... I see, I get it now :)

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...
