If you were asked to calculate the density of a penny, you might have difficulty because
the small amount of water displaced by one penny. How could you modify the
procedure to go about calculating the density of a penny?
"............small amount of water displaced by one penny ......."
So bust the piggy bank and use 100 pennies.
but make sure all of the pennies are the same kind; i.e., old pennies were copper and new pennies are copper clad zinc.
To calculate the density of a penny, you can modify the procedure by using the principle of buoyancy. Here's how you can do it:
1. First, measure the mass of the penny using a scale.
2. Then, measure the volume of the penny using a graduated cylinder.
3. Fill the graduated cylinder with water until it is about halfway full.
4. Take the initial reading by recording the water level.
5. Carefully lower the penny into the water using a pair of tweezers or tongs.
6. Observe the change in water level and record the final reading.
7. Calculate the volume of water displaced by subtracting the initial water level from the final water level.
8. Use the mass of the penny and the volume of water displaced to calculate the density.
The formula for density is: Density = Mass / Volume.
By using the principle of buoyancy, you can calculate the density of the penny by determining the volume of water displaced when the penny is submerged.
