Oil temperature as a function of water temperature
Hi imagine I have a sphere of silicone oil in a sealed metal container. I then fully submerge the container in a bath of ice and water. This is what I have done.
The bath temperature remains at just below zero degrees. However the silicone oil temperature remains around 0.15degrees C. Despite both temperature probes being calibrated.
Any ideas gang?
I thank you in advance.

Could thin thermocouple cable really be responsible for heating the silicone oil temp up by this much?? The cable does run out of the chamber and into to the "outside world", where the room temperature is held around 21 degrees C.
I am not sure....the specific heat capacity of silicone oil is less than water, I don't understand why it's temperature is not the same as the ice and water?
