To determine the density of an irregular solid such as a stone, you can use the method of water displacement. Here's a step-by-step experiment to help you determine the density:
Materials needed:
- Irregular solid (stone)
- Beaker or graduated cylinder
- Measuring scale
- Water
- Paper towels
Procedure:
Measure the mass of the stone using a measuring scale. Record the mass in grams (g) and note it as "m1."
Fill the beaker or graduated cylinder with water until it is about half full.
Measure the initial volume of water in the beaker or graduated cylinder and record it in milliliters (mL). Note it as "V1."
Carefully lower the stone into the water-filled beaker or graduated cylinder. Make sure the stone is completely submerged and does not touch the sides of the container.
Observe the change in water level. The water level will rise due to the displacement caused by the stone.
Measure the final volume of water and record it in milliliters (mL). Note it as "V2."
Calculate the volume of the stone using the formula: Volume = V2 - V1.
Calculate the density of the stone using the formula: Density = m1 / Volume.
Record the calculated density in grams per cubic centimeter (g/cm³).
Dry the stone and the beaker or graduated cylinder with paper towels.
By following this procedure, you can determine the density of an irregular solid like a stone using the method of water displacement. Remember to handle the stone and water with care and ensure accurate measurements to obtain reliable results.
