compare the 3 approaches used to measure the density of the metal. Which would be the most accurate and why?

### Submersion because there are no calculations and there is only one uncertain number measurement read once instead of multiple times

## Step1: Identify the Approaches### There are three approaches to measure the density of a metal: direct measurement, indirect measurement, and submersion.## Step2: Analyze Accuracy of Direct Measurement### Direct measurement involves using a balance to measure the mass and a ruler to measure the volume. This method can be accurate but is subject to human error and the limitations of the measuring instruments.## Step3: Analyze Accuracy of Indirect Measurement### Indirect measurement involves using a known density of a reference material to estimate the density of the metal. This method introduces more uncertainty due to the reliance on external references and potential errors in measurement.## Step4: Analyze Accuracy of Submersion### Submersion involves immersing the metal in a liquid with known density and measuring the displaced liquid volume. This method is less prone to human error and reduces uncertainty because it involves a single measurement of volume and does not require multiple readings.## Step5: Compare Accuracy and Uncertainty### Submersion is the most accurate method because it avoids the need for multiple measurements, reduces human error, and introduces fewer uncertainties compared to direct and indirect measurements.
