Explanation:
According to the heat relationship,
Heat given by steam = heat taken by water
Hence, 
= 
where, 
= specific heat
Value of 
at 250^{o}C and 12.5 atm is 2.326 
.
And, at 200^{o}C and 12.5 atm is 2.743 .
Therefore, average = 
= 2.5345 kJ/Kg^{o}C
As the given data is as follows.
= 400 kg/hr, 
= 
= 
, 
= 500 kg/hr
= 4.186 
Hence, putting the given values into the above formula as follows.
=
= 
As we know that, 
Thus, we can conclude that the new temperature of water is 
.

Oxidation States: 6, 3, 2, 0
Chromium is unstable in oxygen, it immediately produces a thin oxide layer that is impermeable to oxygen and protects the metal below. </span>
Answer:
The steps that must be long to obtain separately the components (to the substances) of a mixture of water, salt and sand, are respectively: A) filtration and siphoning B) decanting and siphoning C) simple filtration and distillation D) collection and decantation.
Simple filtration and Siphoning is the method. When an insoluble solid is present in a liquid. Filtration is the ideal method of separation,The sand is filtered by the filtered paper as water is allowed to pass through the filter paper into a beaker where the funnel which hold the filter paper emptied into.
Water molecules is Siphoned, pull by force of gravity through the sand, past the filter paper to emerge as clean in the beaker below.
