Q-2: Define Soil.
Answer: Soil is a natural mixture of different constituents like organic matter,gases, liquids and minerals.
Q-3: What are the constituents of soil?
Answer: Organic mater,gases,liquids, minerals like quartz, silica and rock weathered compounds.
Q-4: Define Specific Gravity.
Answer: Specific gravity of soil is defined as the ratio of the unit weight of soil to the ratio of the unit weight of water at the same temperature.

Q-13: How would you calculate the moisture content of a soil mass?
Answer: Moisture content is defined as the ratio of weight of water to the weight of soil solids.
Q-14: What is unit weight of soil?
Answer: Unit weight is defined as the weight per unit Volume.
Q-16: What is Density?
Answer: Mass per unit volume is defined as density of soil mass.

Q-18: What are the four states of soil?
Answer: Solid,semi-solid,plastic and liquid.
Q-19: What is Shrinkage Limit?
Answer: Shrinkage limit is the minimum water content at which the soil mass transfers its state from solid to semi-solid state.
Q-20: What is Plastic Limit?
Answer: Plastic limit is the minimum water content at which the soil mass changes its state from semi-solid to plastic state.
Q-21: What is Liquid Limit?
Answer: Liquid limit is the minimum water content at which the soil mass change its states from plastic limit to liquid limit.
Q-22: What is Flow Index?
Answer: The slope of the flow curve is termed as flow index.
