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.

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.

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:
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)
