Question

Soil A has a volume of 297.01 cm3, a wet weight of 498.12 grams, and an oven dry weight of 356.41 grams. It has a liquid limit of 50 and a plastic limit of 20. Soil A has a moist bar length 100 cm and an air-dry bar length of 80 cm.


Soil B has a volume of 297.01 cm3, a wet weight of 529.86 grams, and an oven dry weight of 445.52 grams. It has a liquid limit of 30 and a plastic limit of 22. Soil B has a moist bar length of 100 cm and an air-dry bar length of 95 cm.
For both soils, assume particle density equals 2.65 g/cm3 and density of water equals 1 g/cm3.

2. Which soil (A or B) is a clay loam and which soil (A or B) is a sandy loam? Explain your answer.

3. Which soil (A or B) will have the higher heat of wetting – the property that the soil releases more heat due to the water molecules making and breaking bonds as it moves through the soil profile. Explain your answer.

Thanks!

Answer 1

2. .So A is a sandy loam and soil B is a clay loam.The Soil B clay loam retains more water as compared to the sandy loam water.

3. Soil B will have the higher heat of wetting because it retains more water so for that water molecules making and breaking bonds as it moves through the soil profile.
