Solution
An object will float in a fluid if its density is less than the density of the fluid.
Here's why:
-
Density is defined as mass per unit volume. It determines how much matter is packed into a certain amount of space.
-
When an object is placed in a fluid, it will displace a volume of that fluid.
-
If the object's density is less than the fluid's density, the fluid that is displaced weighs more than the object. This means the buoyant force (the upward force exerted by the fluid) is greater than the weight of the object, causing it to float.
-
If the object's density is greater than the fluid's density, the fluid that is displaced weighs less than the object. The buoyant force is less than the weight of the object, causing it to sink.
-
If the object's density is equal to the fluid's density, the fluid that is displaced weighs the same as the object. The buoyant force equals the weight of the object, causing
