Science Buddies: What's the Point of Boiling?
You know that water can exist in three separate phases: solid (ice), liquid (water), and vapor (steam). To change from one phase to another, you simply add (or remove) heat. When water boils, what happens to molecules (for example sugar...

Serc: Boiling Water Below Its Boiling Point
Mars has such low atmospheric pressure that any water at the surface would boil away. In this activity, students see that they can get water to boil below its "typical" boiling temperature when they drop the pressure in a closed...
