I have noticed even people who claim everything is predestined, and that we can do nothing to change it, look before they cross the road.

Normally when a liquid is heated above its boiling point, it evaporates, turning into a vapor. But when scientists recently performed an experiment on the International Space Station (ISS), they observed that the vapor near a heat pipe condensed into a liquid even when the temperature was 160 K above the substance’s normal boiling point. The results show that microgravity significantly alters the processes of evaporation and condensation, but the scientists do not yet have a complete explanation for the phenomenon.
The research team, consisting of scientists from Rensselaer Polytechnic Institute and the NASA Glenn Research Center, have published a paper on the surprising observations in a recent issue of Physical Review Letters.
This is not the first time that unexpected behavior in heat pipes, which are devices used to cool components of a spacecraft, has been observed in microgravity. In 2015, many of the same researchers made a related, counterintuitive observation during experiments conducted on the ISS.
At that time, the researchers observed that increasing the heat input to a heat pipe did not cause the device to dry out near the heated end as it does on Earth, but instead it caused liquid accumulation there. At the time, the processes responsible for this phenomenon were not completely understood.
