Practical Exercises in Density, Mass, and Volume
This page presents several practical exercises that demonstrate the application of density, mass, and volume concepts, providing ejemplos de densidad en la vida cotidiana and ejercicios de densidad, masa y volumen resueltos pdf.
Exercise 1: Determining Density
Example: Calculate the density of a metal piece with a mass of 980g and a volume of 135mL.
Solution:
Using the fórmula de densidad: D = m / V
D = 980g / 135mL = 7.25g/mL
This exercise demonstrates how to calcular masa y volumen to find density.
Exercise 2: Comparing Coin Densities
This exercise presents three coins with different masses:
- Coin A: 12g
- Coin B: 9.2g
- Coin C: 4.5g
The exercise asks how to determine the volume and density of these coins.
Highlight: Volume can be determined using the principle of Archimedes, and density is calculated by dividing mass by volume.
This problem illustrates the process of como calcular la masa and volume for small, irregular objects like coins.
Exercise 3: Density of Alabaster Figure
Example: An alabaster figure weighing 290g is placed in a 500mL graduated cylinder containing 300mL of water. The water level rises to 410mL. Calculate the density of the alabaster.
Solution:
- Volume of the figure: V = 410mL - 300mL = 110mL
- Mass of the figure: m = 290g
- Density: D = 290g / 110mL ≈ 2.63g/mL
This exercise combines the concepts of densidad de un sólido irregular ejemplos and densidad de sólidos pdf, providing a practical application of the Archimedes principle and density calculation.
These exercises offer valuable practice in applying density formulas and measurement techniques, reinforcing the concepts presented in the previous pages and demonstrating their relevance in real-world scenarios.
