Experiment with Oil

We also observed features of motor oil during the warming up. This kind of motor oil is used for producing other kinds of industrial oils. Considering to its thermal coefficient we expected a faster warming up period and having higher temperature of the solution, which was experimentally confirmed. We stopped the experiment after 4 minutes and 24 seconds. The aim was to compare thermal conductivity in temperature lower than 100 oC. The oil warmed up much faster than water and the warming curve was softer than clean water curve. Temperature differences between the sensors in the bottom and upper side were bigger - we expected that. You can see it on the final screenshot.
