  2. At what temperature do solid ice and liquid water co-exist together?
  3. Why are gases compressible but not the liquids?

  1. Solids and liquids are collectively known as condensed phases because they have very small intermolecular spaces in between their particles than in gases because liquid is condensed form of gas and solid is condensed form of liquid and gas (in case of reverse sublimation).
  2. Solid ice and liquid water co-exist at the melting point of ice and freezing point of water.
  3. In gases, the constituent particles are far apart from one another and have large intermolecular spaces between them as compared to liquids. Hence, gases are compressible but not the liquids.
