Answer:

Explanation:
Hello,
In this case, we find the following states:
a. Liquid salt water at 28.0 °C.
b. Liquid salt water at 102.5 °C.
c. Vapor salt water at 102.5 °C.
The first process (1) is to heat the liquid water from 28.0 °C to 102.5 °C and the second one (2) to vaporize the liquid salt water. In such a way, each process has an amount of energy that when added, yields the total energy for the process as shown below:

Best regards.
Answer:
Follows are the solution to the given question:
Explanation:
Dry Soil weight = solid soil weight = 
solid soil volume =
saturated mass soil = 
The weight of the soil after drainage is =
Water weight for soil saturation = 
Water volume required for soil saturation =
Sample volume of water: 

Soil water retained volume = (draining field weight - dry soil weight)



(Its saturated water volume is equal to the volume of voids)
