The building blocks of life on Earth may have been fueled by tiny sparks hopping between water droplets. Four billion years ...

It evaporates into the air. Show the animation Evaporation. Explain that water molecules leave the liquid state and form water vapor, a gas. The molecules in water vapor become part of the air. The ...

Study discovered that tiny electrical sparks, called microlightning, form when water droplets collide. These can create ...

Much of our waste is far too valuable to simply be incinerated. If it is recycled in a carefully controlled way, not only can ...

If the cup of cold water is not exposed to air, no condensation will form. The fast-moving molecules of water vapor transfer their energy to the side of the cup which is cooler. This causes the water ...

Life may not have begun with a dramatic lightning strike into the ocean but from many smaller "microlightning" exchanges ...

Biomass can be converted into valuable gases. But in order to control this process, the amount of water vapor has to be measured. This is notoriously hard, because other components of the gas can ...

This resulted in the formation of organic molecules with carbon-nitrogen ... the potential power of small bits of water, including how water vapor mayhelp produce ammonia, a key ingredient in ...
