One fine day John was cleaning utensils. He found that the sponge used for cleaning utensils can be compressed easily but the utensils cannot be compressed. He grouped utensils and sponge into two groups. On the basis of which of the following properties, can the utensils and sponge be sorted?
In this situation, we see that the sponge can be pressed and deformed easily but the utensils cannot. In fact, the sponge can even be folded in hand but not the utensils. That means that the sponge is soft but utensils are hard. Hardness is determined by observing the comparative ease or difficulty by which one object is compressed or folded. Hence, we can say that by the property of hardness, we can sort the sponge as well as the utensils into two distinct categories.
