“What I have related is sufficient for establishing the main principle, namely, that the heat which disappears in the conversion of water into vapour, is not lost, but is retained in vapour, and indicated by its expansive form, although it does not affect the thermometer. This heat emerges again from this vapour when it becomes water, and recovers its former quality of affecting the thermometer; in short, it appears again as the cause of heat and expansion.”
About This Quote
This interpretation was drafted with AI assistance. It is one reading of the quote, not the author's own explanation.
Heat is conserved during water's phase change; it disappears as vapor but reappears when vapor condenses back to water, affecting temperature again.
In simple terms: Heat is not lost, it changes form during vaporization and condensation.
Key Takeaway
Recognize energy conservation in phase changes.
