Steam
Steam is the technical term for water vapor, the gaseous phase of water, which is formed when water boils. Water vapor cannot be seen, though in common language it is often used to refer to the visible mist of water droplets formed as this water vapor condenses in the presence of cooler air. Strictly speaking, in terms of the chemistry and physics, true steam is invisible. At lower pressures, such as in the upper atmosphere or at the top of high mountains water boils at a lower temperature than the nominal 100 °C (212 °F) at standard temperature and pressure. If heated further it becomes superheated steam.

Of the supernova burgeoning over the barn,
Lampshine blurred in the steam of beasts, the spirit’s right
Oasis, light incarnate.”
