Yes. That sort of defines "float".
As long as the can of Crisco is less dense than water it can
As long as it can displace a volume of water equal to its mass (ie its density is less than that of the water) it will float. Most paper will have a density less than that of water (or can be so folded) so will float.
false
Items that are less dense than water will float, such as plastic, cork, wood, and certain metals like aluminum. Objects with air pockets or hollow spaces will also float because they displace enough water to remain afloat.
Indefinitely. Someting will float as long as its density is less than that of the fluid it is suspended in. So a baloon will float until the volume decreases to the point it is more dense than air or diffusion exchanges enough gas for the same to happen. Some wood will float in water until it absorbs enough water to no longer be less dense than water.
The Density of the object as long as its .99 grams then it will float because the object has to have less density than water in order to rise above the water.
it will float as long as it is not fully covered water.
Most logs float because the density is less than that of water . (One cubic centimeter of wood weighs (has less mass) less that one cubic centimeter of water (or liquid in which it is placed). However given a LONG time is water, logs can become "waterlogged", soaked through with water and their density becomes greater that of water and they sink.
A boat floats because it is less dense than the water it displaces. The upward force acting on the boat from the water is called buoyancy, which counteracts the force of gravity pulling the boat downward. As long as the weight of the boat is less than the weight of the water it displaces, the boat will float on the surface of the water.
Styrofoam will float indefinitely because it is less dense than water, making it buoyant. This is due to its composition of trapped air bubbles within the material, preventing it from sinking.
Oils, alcohols, and certain types of organic solvents, like acetone, can float on top of water due to their lower density. This causes them to form distinct layers when added to water, with the lighter liquid resting on top.
Ships will float in fresh water as long as their density is lower than that of the water they displace. This is due to Archimedes' principle, which states that the buoyant force acting on an object in a fluid is equal to the weight of the fluid displaced by the object.
