In order for a high temperature boiler or steam engine to produce superheated water, or steam: the heat source must be greater t
Vinil7 [7]

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.

How are states of matter different at an atomic scale?
nalin [4]

Answer:

The bonds that exist between their atoms and molecules differ on an atomic scale.

Explanation:

The three basic states of matter are solid, liquid, and gas. The major difference between them is the strength of the bonds that hold their molecules together. This affects the way that the molecules interact with each other.

The intermolecular forces binding solids together are very strong. This makes solids rigid and not able to move about freely, but rather, only able to vibrate about a mean position.

The intermolecular forces binding liquid atoms together are a lot weaker than that of solids. This makes liquids able to flow.

The intermolecular forces binding gas molecules together are the weakest. As a result, the gases can move about freely and occupy no definite volume.
