1. what where the three major technological developments discussed in this portion of the course?

How does the pressure inside a sealed container of steam change as the steam temperature is cooled and condensed into water?

When matter turns from its gas phase back into its liquid phase, the molecules take up much less space and exert far less pressure. In fact, the condensing steam creates a partial vacuum—a region of much lower pressure than that of the surrounding atmosphere—inside the bottle.Apr 25, 2013
