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 'Using battery energy to heat a battery…'

Problem: You’re an Uber driver with a Tesla Model 3. Today’s low: 30F, high: 65F. You want to reach a USD$ profit target in the least number of hours, but your choices could have added cost. Do you preheat the battery only when you are headed to the charging station (to increase the charging rate by warming the battery — however the battery might not be “warm enough” when your reach the charger and thus slower charging rates), or do you always “navigate to the charger” the entire day (which...
