![**Question: Determining the Plasticity Index (PI)**
A soil sample was tested for its liquid limit (35%) and plastic limit (25%). What is the plasticity index (PI)?
- ○ 10
- ○ 15
- ○ 20
- ○ 25
**Explanation:**
The Plasticity Index (PI) is calculated as the difference between the liquid limit (LL) and the plastic limit (PL):
\[ \text{PI} = \text{LL} - \text{PL} \]
Given:
- Liquid Limit (LL) = 35%
- Plastic Limit (PL) = 25%
Calculation:
\[ \text{PI} = 35\% - 25\% = 10\% \]
The correct answer is 10.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fb2d7e9b1-7208-47e7-acf1-5a4d04c3ff3b%2F2456efe2-0a34-46ec-bd3f-4a4969d2a4eb%2Fy722j78_processed.png&w=3840&q=75)
