Web13 aug. 2024 · The natural tendency of a system is for its entropy to increase. Figure 11.4. 1: The messy room on the right has more entropy than the highly ordered room on the left. The drive toward an increase in entropy is the natural direction for all processes. Chemical reactions also tend to proceed in such a way as to increase the total entropy of the ... WebYou can also freeze pure water by putting it into a vacuum. Water will boil when the vapor pressure exceeds the ambient pressure, and in a vacuum, this is the case at all temperatures for which the water is liquid. Boiling is endothermic (it takes energy to boil water), and so the water cools off as it boils. Eventually, what’s left will freeze. imdb gone fishing
