Answer:
Explanation:
The thermocol is light in weight and is a like a sponge only ....
due to differences in density.
If the object has more density than water then it will sink in water. Example of such objects is- rock, marble, steel, iron, copper, nickel, gallium, sand, beryllium and mercury. On the other hand, objects that have a lesser density than water then the object will float in water.
If an object weighs more than an equal volume of water, it is denser and will sink, and if it weighs less than an equal volume of water, it is less dense and will float.
hope it helps u : )
