Density, Buoyancy, and Volume

Volume

  • Volume is measured in liters or milliliters.
  • Volume is the measure how much space matter takes up.

WSQ

  • To find the volume of a a regular shape, measure the length, width and height. Then, multiply them together.
  • To find the volume of an irregular shape, place the shape in a measured amount of water and calculate the change of the displaced water.
  • Write your summary and write down questions you want answers to.

Buoyancy

What if the object has the same density as the fluid?

  • Buoyancy is an upward force by a fluid that opposes the weight of an immersed object.
  • Objects of a material of higher density than the fluid can still float if it has a shape that allows a lower density matter below the surface level of the fluid. Ships have empty spaces of air.

Density Defined

Maybe this can help...

Archimedes

Principle

  • Density is the concentration of matter in an object.
  • Density can determine if an object will sink or float.
  • Mass and volume of an object can be measured and used to determine the density of an object.
  • If the object has a density greater than the fluid, it will sink. If the density is less, the object will float.

Density is calculated by using the following formula:

Density = mass ÷ volume

The formula to calculate the density of a substance.

  • p is the lower case Greek letter for density
  • m is mass, which the amount of matter in a body. (kg)
  • V is volume, which the space a substance occupies or contains. (m3)
