4. limit determined for both undisturbed and remoulded soils.
6. plasticity index of soil sample is 4 times flow index find the toughness index.
7. Swedish agriculturist who divided the range of consistency from liquid to solid state.
10. material obtained due to weathering of volcanic ash.
12. A soil has porosity of 30%. Its voids ratio in the loosest and densest state is 0.35 and 0.92 respectively Justify its density index(answer approximately-rounding off).
13. minimum water content when soil begins to crumble when rolled into threads of 3mm diameter.
18. clay mineral whose structural units are held by potassium bond.
20. force also called as gravitational force.
21. Solve for the time of settlement of coarse particle of a soil sample of diameter 0.5(take γ=0.905D2 and height of water tank as 5 m and answer in integer).
23. method to determine water content accurately.

1. sensitivityranges from 8-16.
2. person who gave the flow through capillary idea.
3. most uniform soil deposit.
4. In sedimentation analysis, identify the soil fraction in micron size, so as to be kept in a liquid medium (water).
5. law based on sedimentation.
6. identify the formula If=w1-w2/log(N2/N1).
8. The mass and volume of saturated soil sample is 30.8gm and 18.8cc respectively On oven drying mass reduces to 20gm and volume by 9.9cc.Solve for shrinkage ratio(answer an integer only).
9. relative compaction when the soil is in loosest form density index is zero(answer in percentage).
