Usage Examples
  • (The salt can be made to separate out as a solid when the solution cools.)
  • (Metal ions can be forced to form a solid deposit through chemical reaction.)
  • (Only some dissolved substances can be made to settle out as a solid.)
Advanced Usage
  • "precipitable water": In meteorology, this term refers to the total amount of water vapor in a vertical column of the atmosphere, expressed as the depth of liquid water that would result if all the vapor were condensed and precipitated.
    • The forecast indicated high levels of precipitable water, suggesting heavy rainfall. (The atmosphere contained a large amount of vapor that could turn into rain.)
  • "precipitable solid": In chemistry, a solid that can be formed through a precipitation reaction.
