When water molecules do this, they change from liquid water to water vapor – a gas. This changing from a liquid to a gas is called evaporation. Heating a liquid causes the water molecules to move ...

Cheeky. When water is heated up, it changes state from a liquid to a gas, called steam. And this process is called evaporation. When a gas cools down, it can change state back into a liquid.

The focus is that matter, whether solid, liquid, or gas, is made up of particles; that dissolving and evaporation happen at the particle level; and that models can help explain these processes that we ...

For certain gases, this turned the gas into a liquid. In the next step ... which, upon partial evaporation, achieved an even lower temperature. By repeating this sequence, scientists approached ...
