how do you find the density of and an object that has been droppped into water
To find the density of an object that has been dropped into water, you need to know its mass and volume. Here's how you can determine its density:
1. Measure the mass of the object: Use a scale or balance to measure the mass of the object in grams (g) or kilograms (kg). Make sure to remove any excess water or moisture from the object before measuring its mass.
2. Measure the volume of water displaced: Fill a container with water and measure its initial volume, preferably in milliliters (ml) or cubic centimeters (cm³). Gently lower the object into the water and record the new volume of the water. The difference between the initial and final volumes represents the volume of water displaced by the object.
3. Calculate the density: Now that you have the mass and volume, you can calculate the density using the formula: Density = Mass / Volume. Make sure to use the appropriate units for mass (g or kg) and volume (ml or cm³) to ensure the density is expressed correctly.
Remember, the density of water is approximately 1 g/ml or 1 g/cm³. If the density of the object is less than 1 g/ml, it will float in water, whereas if it is greater than 1 g/ml, it will sink.
By following these steps, you can find the density of an object dropped into water.
