KER Plunk!
Water 1.00 gram/cm^3
Density = Mass/ Volume
Radius = Diameter / 2
What is the most sand
you could place in the film container and prevent it from sinking?
Step 1: Determine the volume of the film container.
Volume of film container = Pi * (Radius^2) * Height.
Volume of film
container = 3.14 * (___________cm ^2) * (___________) cm. =
_________ cm^3
Step 2: Determine how
much sand can you safely put in the film container without it sinking?
Remember: The
Density of Water is 1.000 gram/cm^3
_________
grams of sand.
Step 3: Determine the
Density of the film container.
Density of film
container = Mass/ Volume
Density = (__________) grams of sand Mass/ (___________)
cm^3 Volume film container:
see step 1.
Density =
(__________) grams/cm^3
Carefully lower the film
container in the presence of your teacher.
