Density

• Density in physics

  • Measured in kilos per meter cubed
• Multiple measurements can help identify anomalies and calculate a mean for density
• Larger volume measurements lead to more accurate density calculations by minimizing measurement uncertainties
• Example calculation: Volume of 420 kilos of aluminium with a density of 2,710 kilos per meter cubed is 0.155 meters cubed
• Calculating density of a solid experimentally

  Find mass and volume of the object. For regular shapes, find volume by multiplying length, width, and height. For irregular shapes, use a eureka can filled with water and a measuring cylinder to measure the volume
• 1 gram per centimeter cubed is equivalent to 1,000 kilos per meter cubed
• Finding density


  Density is a measure of how much mass a substance has per unit of its volume. To find density, divide the substance's mass by its volume
• Density


  Measure of how much mass a substance has per unit of its volume
• Calculating density of a liquid experimentally

  Place an empty measuring cylinder on a balance, zero the balance, pour the liquid into the cylinder, record the mass, then divide the mass by the volume to find density
• Common density unit

  • Kilos per meter cubed
  • Grams per centimeter cubed
