What is the Joule-Thomson effect?
The Joule-Thomson effect describes the decrease in temperature of real gases when they expand against a lower pressure!
In the article Free expansion of an ideal gas in a vacuum it was...
Why does water boil faster at high altitudes?
Due to the lower pressure, the boiling point of water decreases and the water boils earlier at high altitudes.
