How does an object float or sink when placed on the surface of a liquid?
Answers
This is because the buoyant force acting on the object is less than the weight of the object. If the density of the object is less than or equal to the density of the liquid, then it floats on the surface of the liquid. This is because the buoyant force acting on the object is equal to the weight of the object.

If an object has a higher density than the fluid it is in (fluid can mean liquid or gas), it will sink. If it has a lower density, it will float. 2. If something's density is lesser than the water's density, then it will float on water's surface, otherwise it will sink.
Objects like apples, wood, and sponges are less dense than water. They will float. Many hollow things like empty bottles, balls, and balloons will also float. That's because air is less dense than water.
Compare the density of the object in question to the density of water. If its density is less than water, it will float. ... If the density of an object is greater than water, it will sink.
Lighter liquids (like water or vegetable oil) are less dense than heavier liquids (like honey or corn syrup) so they float on top of the heavier liquids.
