How are mass and volume related?
Mass measures the amount of matter in a substance or an object. Volume measures the amount of space that a substance or an object takes up. The basic SI unit for volume is the cubic meter (m3).
What is the volume of the object?
Volume is the measure of how much space there is within a three-dimensional object.
Why do objects float or sink in liquids?
The density of an object determines whether it will float or sink in another substance. An object will float if it is less dense than the liquid it is placed in. An object will sink if it is more dense than the liquid it is placed in.
What makes something buoyant?
When an object enters water, it pushes out water to make room for itself. The object pushes out a volume of water that is equal to its own volume. If the object displaces an amount of water equal to its own weight, the buoyant force acting on it will be equal to gravity—and the object will float.
What material is most buoyant?
Hydrogen gas
What do you mean by buoyant?
1a : the tendency of a body to float or to rise when submerged in a fluid testing an object’s buoyancy. b chemistry : the power of a fluid to exert an upward force on a body placed in it the buoyancy of water also : the upward force exerted.
How does buoyancy affect the weight of an object?
An object will float if the buoyancy force exerted on it by the fluid balances its weight, i.e. if FB=mg F B = mg . But the Archimedes principle states that the buoyant force is the weight of the fluid displaced. So, for a floating object on a liquid, the weight of the displaced liquid is the weight of the object.
How much of an object is submerged?
For example, for an object of mass 160 grams and a volume of 200 cm^3, the density is 0.8 gm/cm^3. 2) Divide density of object by the density of the liquid and express as a % to get % submerged. For floating in water of density 1.0 gm/cm^3, dividing yields 0.8 or 80% of the object is submerged.
