SUMMARY
The discussion revolves around calculating the increase in entropy produced by an 82-kg parachutist descending 350 meters at a constant speed, with an air temperature of 21 degrees Celsius. The relevant equation used is S = Q/T, where Q represents the heat transfer and T is the temperature in Kelvin. The participant calculates the work done using W = mgh, resulting in 281,547 J. The participant seeks guidance on determining the heat transferred and the appropriate temperature to use in the entropy calculation.
