GENERAL KNOWLEDGE

Detailed explanation-1: -Density is a measure of how heavy something is compared to its size. If an object is more dense than water it will sink when placed in water, and if it is less dense than water it will float. Density is a characteristic property of a substance and doesn’t depend on the amount of substance.

Detailed explanation-2: -The net upward force on any item in any fluid is known as buoyant force. The object will rise to the surface and float if the buoyant force is higher than its weight. The object will sink if the buoyant force is less than its weight. Buoyancy is a force acting on an item that causes it to rise or move higher.

Detailed explanation-3: -If an object’s density is higher than the density of water, it will sink. On the flip side, if an object is less dense than water, it will float.

Detailed explanation-4: -The things that float are lighter than water. The things that sink are heavier than water. The eraser, sharpener, steel spoon and the compass sink in the water while a plastic ruler, pencil and a rubber band floats.

Detailed explanation-5: -The relative densities of an object and the liquid it is placed in determine whether that object will sink or float. An object that has a higher density than the liquid it’s in will sink. An object that has a lower density than the liquid it’s in will float.
