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
