The discussion centers around the appropriateness of measuring temperature change at a rate of 100K/s in thermal physics. Participants agree that while the approach to the problem is correct, the resulting temperature change is excessively high, being three orders of magnitude too large. The calculations indicate that with a power input of 10,000 J per second, the temperature would indeed rise by approximately 100 K each second, which is deemed intuitively offensive. The consensus is that such a rapid rate of heating is unrealistic and would not be sustainable. Overall, the conversation emphasizes the need for careful attention to detail in thermal calculations.
