Given:
The solution decreased by  ounces every hour for 5 hours.
 ounces every hour for 5 hours.
Remaining solution at the end of the experiment =  ounces.
 ounces.
To find:
The initial amount of solution.
Solution:
Let the initial amount of the solution be x.
The solution decreased by  ounces every hour for 5 hours.
 ounces every hour for 5 hours.
Total decreased amount  
                                           
Initial amount = Remining amount + Decreased amount of solution.




Therefore, the initial amount of solution is 18 ounces.

<span>Evaporation and transpiration.
</span>
The evaporation process uses the sun radiation or sun’s
thermal energy for vaporization of a water from the land or soil to be water
vapor then in the air. Transpiration on the other hand is the same with evaporation
that involves water molecules to be vaporized into the air but it is located in
the stoma of the plants. It is like evaporation within plants. This is actually
to have homeostasis in plants and still part of the water cycle.
