I think some of the additional heat also has to warm the water to more than 60 ºC (since the temperature of the water also goes up with the temperature of the device). > So, the slope of the >curve at that point corresponds to however much heat is being generated >by the reaction, applied solely to warming the device (as, again, the >heater's output is sufficient to warm the water to that temperature). >I've drawn a tangent line to the curve at 60 degrees in blue.
