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.
Answer: Positive charge
Explanation:
An atom consists of electron (negatively charged), Proton (Positively charged) and neutron (no charge).
The proton (+) and the neutron (no charge) are in the nucleus of the atom. this makes the resulting charge of the nucleus positive while electron (-) is outside the nucleus.
