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.
There are three methods of heat transfer
The concentration refers to the amount of substance that is contained in solution.
<h3>What is the concentration?</h3>
The concentration refers to the amount of substance that is contained in solution. We can be able to obtain the concentration of the raw acid by the use of the relation;
Co = 10pd/M
M = molar mass of the acid
p = percentage of the acid
d = density of the acid
Co = 10 * 36 * 1.18/36.5
Co = 11.6 M
Using the dilution formula;
C1V1 = C2V2
10 * 11.6 = C2 * 1000
C2 = 10 * 11.6/1000
C2 = 0.116 M
Using again;
C1V1 = C2V2
0.116 * 5 = C2 * 20
C2 = 0.116 * 5 /20
C2 = 0.029 M

Explanation:
Having dimples is the dominant trait which means if he is heterozygous, the dominant trait will still show. So it can be homozygous dominant or heterozygous.
Petrified fossils, they are made of wood that becomes petrified from pressure and lack of oxygen.
