1

When do objects float in water?

When the object is less dense than the water displaced by it.

2

State the eqaution for density. Gvie appropriate units.

3

Describe a method to determine the density of a regular solid

  • Take measurements of relevant dimensions using a ruler
  • Calculate the volume using an appropriate equation
  • Measure mass using a balance and calculate density using density = mass/volume 

4

Descirbe a method to determine the density of an irregular solid

  • Measure volume by submersion: read the volue of liquid, submerge the solid, then read the change in volume (which would equal volume of object)
  • Measure mass using a balance 
  • Use density = mass/volume to calculate density 

5

Descrieb a method to determine the density of a liquid

  • Place an empty beaker on top of a balance and zero the device 
  • Pour liquid into the beaker to determine the mass 
  • Pour the same liquid into a measurong cyclinder and read off the volume 
  • Use density = mass/volume to calculate density
