Answer:

COLD WATER

Explanation:

  • The solubility of a gas increases with decrease in the temperature.

Also the solubility of a gas increases with increasing pressure.

  • A gas can be compressed by increasing the pressure and decreasing the temperature.
  • FOR example the gas in domestic LPG cylinders are in compressed form inside the cylinder.
  • A gas takes the form of a liquid after compressing. Whenever it comes back to normal temperature and pressure it takes back to its gaseous form back.

The gaseous oxygen is water soluble and does not react with it

                    O2 + 2H2O + 4 e= 4 OH-
