Answer:
To find the volume of an irregular solid using a Eureka can, you can follow this simple experiment:
### Materials Needed
1. Eureka can (displacement can)
2. Graduated cylinder or measuring jug
3. Irregular solid object (e.g., a rock)
4. Water
5. Tray or basin (to catch overflow water)
6. Towel or cloth (for drying the object)
### Steps
1. **Fill the Eureka Can**: Fill the Eureka can with water until it starts to overflow from the spout. Make sure to place the can on a stable surface.
2. **Catch the Overflow**: Place a tray or basin under the spout to catch any overflow water. Wait until the water stops dripping from the spout. This ensures the water level is at the spout level.
3. **Place the Graduated Cylinder**: Place an empty graduated cylinder or measuring jug under the spout to collect the displaced water.
4. **Submerge the Object**: Carefully lower the irregular solid object into the Eureka can, ensuring it is fully submerged. Be careful not to splash any water out of the can.
5. **Collect the Displaced Water**: As the object is submerged, water will overflow through the spout into the graduated cylinder or measuring jug. Wait until the water stops dripping.
6. **Measure the Volume of Displaced Water**: Once the dripping stops, measure the volume of water collected in the graduated cylinder or measuring jug. This volume is equal to the volume of the irregular solid.
### Example Calculation
Suppose you collected 150 mL of water in the graduated cylinder. This means the volume of the irregular solid is 150 mL or 150 cm³ (since 1 mL = 1 cm³).
### Important Tips
- Ensure the object is completely dry before submerging it in the water.
- Make sure there are no air bubbles clinging to the object as it could affect the accuracy of the volume measurement.
- Perform the experiment carefully to avoid splashing water out of the can during submersion.
This simple yet effective method leverages the principle of water displacement to measure the volume of irregularly shaped objects.
