Sublimation is a phase transition that occurs when a solid changes into a gas — or, as chemists say, when a solid sublimes. In this activity, students will explore sublimation by conducting ...

One might expect water to evaporate much faster than ice. Surprisingly, researchers from the University of Amsterdam have now shown that for small droplets of ice, this is not the case: ice and ...

Dry ice looks a bit like regular ice. While it can be clear, it’s usually white because water vapor freezes into frost on its surface. Dry ice is very cold. It’s −78.5 °C or −109.2 °F ...
