density

• What is density a measure of?


  Density is a measure of how much mass a substance has per unit of its volume.
• How do you calculate density?

  Density is calculated by dividing mass by volume.
• In what units is density typically measured in physics?

  Density is typically measured in kilograms per meter cubed (kg/m³).
• What is the density of solid aluminum?

  The density of solid aluminum is 2710 kg/m³.
• How do you convert density from grams per centimeter cubed to kilograms per meter cubed?

  To convert, remember that 1 g/cm³ is equivalent to 1000 kg/m³.
• What is the first step in calculating the density of a solid experimentally?

  The first step is to find the mass of the solid.
• How do you find the volume of a regular solid?

  You find the volume by measuring and multiplying its length, width, and height.
• What is the volume of a cuboid with dimensions 4 cm, 3 cm, and 2 cm?

  The volume is $4 \times 3 \times 2 =$$24 \text{ cm}^3$.
• How do you find the volume of an irregular solid?

  You find the volume using a eureka can and measuring cylinder.
• How do you calculate the density of a liquid experimentally?

  You place an empty measuring cylinder on a balance, zero it, pour in the liquid, and then divide the mass by the volume.
