1. What Is Water Displacement Method?

The water displacement method is a technique used to measure the volume of an irregularly shaped solid by submerging it in water and measuring the volume of water displaced. This method is based on Archimedes' principle.

2. How Does The Calculator Work?

The calculator uses the water displacement formula:

Where:

• \( V_{solid} \) — Volume of the solid (cm³)
• \( \Delta V_{water} \) — Change in water volume/level (cm³)

Explanation: When a solid is submerged in water, it displaces a volume of water equal to its own volume. By measuring the change in water level, we can directly determine the volume of the solid.

3. Importance Of Volume Calculation

Details: Accurate volume measurement is essential in various scientific fields including physics, chemistry, and engineering. It helps determine density, buoyancy, and material properties of objects.

4. Using The Calculator

Tips: Enter the change in water volume/level in cm³. The value must be positive and greater than zero. The calculator will compute the solid volume directly from this measurement.

5. Frequently Asked Questions (FAQ)

Q1: Why use water displacement instead of direct measurement?
A: Water displacement is ideal for irregularly shaped objects that cannot be easily measured with rulers or calipers.

Q2: What types of solids can be measured with this method?
A: This method works for any solid that doesn't dissolve in water and has a density greater than water.

Q3: How do I measure the change in water volume?
A: Use a graduated cylinder, measure the initial water volume, submerge the object, then measure the new water level. The difference is ΔV_water.

Q4: Are there limitations to this method?
A: The method may not work for porous materials, objects that float, or materials that absorb water.

Q5: Can this method be used for density calculations?
A: Yes, once you have the volume from water displacement and measure the mass, you can calculate density using ρ = m/V.
