True or False: The density of an object affects whether it will float or sink in a fluid.
Remember how we classified objects in class!
An aquarium holds 2000 cm³ of water. A rock with a density of 3 g/cm³ is submerged in it. What is the total weight of the water displaced, and how does it affect the water level of the aquarium?
Use principles of density and volume relationship to find the answer.
A hollow metal sphere filled with air has a density of 0.5 g/cm³ and a mass of 500 g. Will it float on water? Explain why or why not based on Archimedes' Principle.
Remember how density affects buoyancy and the relationship between weight and displaced volume.
