[24 points] A sample of soil has a total volume of 205 cm3. The soil mass when saturated is 361 g. A specific yield test was conducted on the soil by allowing the sample to drain for 24 hours. After drainage the sample mass was 295 g. The soil was then dried and weighed 284 g. What are the specific yield [8 points], specific retention [8 points], and porosity [8 points] of the sample

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)

step-by-step explanation:

whole numbers, zero or greater

answer : one can design an experiment using a liquid and an additive that can be added to the liquid and observe the chemical changes in the reaction species.

one would need a beaker which is filled with a known amount of the liquid in which thermometer is placed to measure the temperature changes; after addition of the additive to the liquid solution one can note down the temperature change and find whether the reaction is endothermic or exothermic in nature. by subtracting the initial temperature value with the final temperature one can find the temperature changes.

various combinations of liquid and additive can be used. liquid in this case can be a known quantity of water and additives can be epsom salt or without epsom salt the experiment can be conducted to notice the changes. water and ice, hydrogen peroxide and dry yeast, vinegar and baking soda,etc.
