**Solution:**
Given,
- Weight of oven dry sand = 500 gm
- Weight of air dry sand = 520 gm
- Weight of sand under saturated but surface dry condition = 525 gm
We need to find the water absorption of sand.
**Definition of Water Absorption:**
Water absorption is defined as the increase in weight of a material (sand in this case) due to the presence of water molecules.
**Calculation of Water Absorption:**
- Water absorption = Weight of sand in saturated but surface dry condition - Weight of oven dry sand
- Water absorption = 525 gm - 500 gm
- Water absorption = 25 gm
Therefore, the water absorption of sand is 25 gm.
**Explanation:**
- Oven dry sand refers to the sand which is completely dry and has no moisture content in it. The weight of oven dry sand is 500 gm.
- Air dry sand refers to the sand which is dried in open air under natural conditions. The weight of air dry sand is slightly more than the weight of oven dry sand due to the presence of moisture content in it. The weight of air dry sand is 520 gm.
- Saturated but surface dry condition refers to the sand which is fully saturated with water but the surface of the sand appears to be dry. In this condition, the sand has absorbed water molecules and its weight has increased. The weight of sand under saturated but surface dry condition is 525 gm.
- Water absorption is the increase in weight of sand due to the presence of water molecules. It is calculated as the difference between the weight of sand in saturated but surface dry condition and the weight of oven dry sand.
- In this case, the water absorption of sand is 25 gm. This means that the sand has absorbed 25 gm of water molecules.
Given,
- Weight of oven dry sand = 500 gm
- Weight of air dry sand = 520 gm
- Weight of sand under saturated but surface dry condition = 525 gm
We need to find the water absorption of sand.
**Definition of Water Absorption:**
Water absorption is defined as the increase in weight of a material (sand in this case) due to the presence of water molecules.
**Calculation of Water Absorption:**
- Water absorption = Weight of sand in saturated but surface dry condition - Weight of oven dry sand
- Water absorption = 525 gm - 500 gm
- Water absorption = 25 gm
Therefore, the water absorption of sand is 25 gm.
**Explanation:**
- Oven dry sand refers to the sand which is completely dry and has no moisture content in it. The weight of oven dry sand is 500 gm.
- Air dry sand refers to the sand which is dried in open air under natural conditions. The weight of air dry sand is slightly more than the weight of oven dry sand due to the presence of moisture content in it. The weight of air dry sand is 520 gm.
- Saturated but surface dry condition refers to the sand which is fully saturated with water but the surface of the sand appears to be dry. In this condition, the sand has absorbed water molecules and its weight has increased. The weight of sand under saturated but surface dry condition is 525 gm.
- Water absorption is the increase in weight of sand due to the presence of water molecules. It is calculated as the difference between the weight of sand in saturated but surface dry condition and the weight of oven dry sand.
- In this case, the water absorption of sand is 25 gm. This means that the sand has absorbed 25 gm of water molecules.
