The image shows two graduated cylinders (measuring cylinders) used to determine the volume of a solid object using the
water displacement method.
Step-by-step Analysis:
1.
Left Cylinder:
- Contains water only.
- The water level is at
30 mL.
2.
Right Cylinder:
- Contains the same amount of water, but now a rock (solid object) has been submerged in it.
- The water level has risen to
40 mL.
---
Goal:
To find the
volume of the rock.
---
Principle:
When an object is submerged in water, it displaces a volume of water equal to its own volume.
So:
- Initial water level = 30 mL
- Final water level (with rock) = 40 mL
- Volume of rock = Final volume – Initial volume
= 40 mL – 30 mL =
10 mL
---
Answer:
The volume of the rock is
10 milliliters (mL).
> 💡 Note: 1 mL = 1 cm³, so the volume is also
10 cm³.
---
✔ Final Answer: 10 mL
