Sentences with phrase «when electrons flow»

Hydrogen atoms are formed in such devices only when electrons flow into a fluid where they can combine with hydrogen ions; those atoms in turn combine with each other to create hydrogen gas.

Not exact matches

For example, when certain materials are cooled to frigid temperatures, electrons team up so they can flow uninhibited, without losing any energy at all — a phenomenon called superconductivity.

We know that life, when you boil it right down, is a flow of electrons: «You eat sugars that have excess electrons, and you breathe in oxygen that willingly takes them.»
