volume of charcoal
Displacement is not suitable for determining the volume of charcoal because displacement is a method that involves measuring the change in volume of a liquid or gas when an object is submerged in it. It is not directly applicable to measuring the volume of a solid substance like charcoal.
To determine the volume of charcoal, you can use a method called "geometric measurement." Here's how you can do it:
1. Choose a container with known volume: Start by selecting a container with a known volume; this could be a beaker, graduated cylinder, or any other vessel with clear markings for measuring volume.
2. Fill the container with a liquid: Pour water or any other suitable liquid into the container until it reaches a certain level, and take note of the initial volume (V1) indicated by the container's markings.
3. Add the charcoal to the liquid: Carefully add the charcoal to the liquid in the container until it is fully submerged. Make sure to avoid unwanted air bubbles and ensure the charcoal is soaked.
4. Measure the new volume: Take another reading of the volume (V2) indicated by the container after adding the charcoal. Subtract the initial volume (V1) from the final volume (V2) to get the volume of the charcoal.
Volume of Charcoal = V2 - V1
Note: When using this method, it's important to account for any water absorbed by the charcoal. You can estimate this by subtracting the mass of the container with the charcoal from the mass of the same container filled with water.
Remember, if the charcoal is irregularly shaped or crushed into smaller pieces, it may be challenging to accurately measure its volume. In such cases, other methods like displacement in a graduated cylinder or the water displacement method can be considered.
