Sunder Was some of the water turning to steam at the bottom of the pan and riseing up turbulating the upper levels?


This can't happen

#1 because the water was not boiling, and #2 as soon as the steam was fully surrounded by liquid again, it would have cooled and turned to the temp that the rest of the water is.

AND because I used the same pan both the substances would have done the same thing negating the results.

AND assuming that the antifreeze boils hotter, it would have seam that the water got hotter faster than the antifreeze because it boiled first...

Pressure, especially low pressure, does not effect the specific heat to a large enough degree to matter because the pressure is uniform.

In order for your experiment to work you must force a fixed flow rate. That means you need to fix the thermostat in a certain position. You could pull the T-stat and run some open tests, but then the flow rate will be so high that the coolant will not be in contact with the hot parts long enough to efficiently conduct heat.
