No the band heater is at 900C but that metal block talk was only for illustrative purposes. Newtons LAw is irrelevant. An insulated metal block that loses heat at a rate of 1W loses heat at the rate of 1W. You mention lack of monotonicity but what's the example (be specific, post link). ----- Original Message ----- From: Jed Rothwell To: [email protected] Sent: Sunday, October 09, 2011 8:14 PM Subject: Re: [Vo]:Look at the BIG PICTURE and you will see this is irrefutable proof

I heat a block of steel to 900C, then I stop heating it, and drop a gram of water on it. What's the temperature? 900C. Notice there was no precipitous drop. Please see Newton's law of cooling: https://www.math.duke.edu/education/ccp/materials/diffcalc/ozone/ozone1.html The other point you are overlooking is the drop is monotonic, that is "Varying in such a way that it either never decreases or never increases." When heat is released from a system the way you describe, the temperature can only drop. It NEVER NEVER RISES. That is a fundamental physical law. Note also that this device was at 80 deg C, not 900 deg C. - Jed
