Density:
Write the equation to find the density of an object___________________________
If the mass of a substance is 10g and its volume is 5 ml what is its density?______________
If an object is denser than water it would ______________ in water. (sink or float)
If an object is less dense than water it would _____________ in water. (sink or float)
The unit for density is _________________________ or ________________________
If you have 2 samples of the same substance, but they are different sizes are their densities different or the
same?
______________________________________________________________________________
True or False:
__________changing temperature changes its density. Hot=less dense & Cold=more dense
__________moving an object changes its density
__________cutting an object changes its density
