Yes, the real reason is that it was late at night when I typed the data into the machine, and I had burned my fingers on one of the hot pans, and as a result I got distracted and got the "hot" and "cold" temperatures reversed. Not even in California is 60F "hot" while 135F is "cold". Here is the true table, which has the "Initial temp" numbers unreversed: Initial Time to Kilojoules joules/ <-- you can think of temp boil absorbed second this number as the Hot water 135F 204sec 184 901 "boiling efficiency" Cold water 60F 365sec 347 950 -- Brian Reid decwrl!glacier!reid Stanford reid@SU-Glacier.ARPA
