Question

In order for a high temperature boiler or steam engine to produce superheated water, or steam: the heat source must be greater than 100°C the water must be permitted to evaporate quickly the system must be sealed and become pressurized above atmospheric pressure the vapor pressure must be kept below 760 mm(Hg)

Answer 1

Answer:

the heat source must be greater than 100°C

the water must be permitted to evaporate quickly

the system must be sealed and become pressurized above atmospheric pressure

the vapor pressure must be kept below 760 mmHg

Explanation:

A superheated water is a dry form of steam in which hydrogen bonds that strongly binds the molecules of water has been overcome.

Superheated water finds application in a wide range of places. For example they are used for sterilization of clinical equipment.

• To produce steam or superheated water, the temperature of the source must be greater than the boiling temperature and less than the critical temperature at 374°C.
• Since superheated water is steam and steam is water in gaseous form. The water must be made to evaporate more quickly than it should condense back.
• High pressure and sealing the system helps to produce superheated water very fast.
• If the pressure between the vapor is kept low, water will boil faster.
