Define Super critical water?
Answers
Answer:
Supercritical water is found on Earth, such as the water issuing from black smokers, a type of underwater hydrothermal vent. In a range of industrial and laboratory processes, they are used as a substitute for organic solvents.
Explanation:
Super critical water is a sample of water that has been heated above 374.15°C and has its pressure above 22.1 mega pascals, it is beyond the critical point of water. Under such conditions, the boundary that exists between water and water vapor becomes indistinguishable and cannot be differentiated. Also, water exhibits properties of a non-polar solvent with a very low dielectric constant, it also dissolves Oxygen and other non polar covalent compounds readily in its supercritical state, contrary to the known properties of water as a polar solvent with high dielectric constant under normal conditions.
Under such high conditions of temperature and pressure, water can be used as an organic, non-polar solvent.
