Although in-situ temperature t defined by ITS-90 is generally the quantity we measure, it is not the most useful variable for describing heat content itself. Two effects can cause problems.
According to the In-Situ Heat Pump Performance report from ... are just the way it feels when there is less heat, and that temperature can always get lower unless it were to reach absolute zero.
The development of new techniques enabling in-situ observation of how heat flows through the nanostructures of materials had therefore been anticipated. This research team developed a nanoscale ...
