Whether an object will sink or float in a fluid is determined by what?

Answer 1

Sinking or floating is determined by the density of the liquid and the density of the object. Density is mass/volume.

When you place an object in a liquid, a certain amount of volume is displaced by the object. If that object puts more mass into the volume displaced than what the original mass was of the liquid in that volume was, then the object will sink.

Therefore an object that is more dense than a liquid will sink.

Answer 2

Whether an object will float in a fluid is determined by the relative density. A less dense object will float in a fluid that is more dense. A balloon filled with air will float in carbon dioxide gas.

Answer 3

Whether an object will sink or float is determined by the object's Density. Objects that are denser than their surroundings can slip through the molecules that are around them, and they are drawn down by gravity until it hits something that is of equal or greater density than that object. For Example, Styrofoam is less dense than water, this means that it can't slip in between the water molecules underneath it. So, as a result it is forced to float on top of the water. A rock, however, is much denser than water, so it can easily slip through the water molecules until it hits the bottom of the container.

Answer 4

#1 -- the density of the particular object

#2 -- the density of the particular fluid

Answer 5

the weight of it and is it is a small area and very heavy it will sink eg. a piece of play doe witch is small but heavy will sink

something that wont sink is a crisp packet
