Read the list of substances. spoon, styrofoam cup, scissors, pencil which substances are likely to float in water?

Explanation:

Density is defined as the mass present in a unit volume of a substance.

Mathematically,       Density =

Since, density is proportional to mass. So, more is the mass of an object more will be its density and vice-versa.

It is known that density of water is 1 g/ml. And any substance that has more density than water will sink into water when added to it. Whereas a substance that has less density than water will float in water when added to it.

Out of the given options density of a styrofoam cup is the least.

Hence, we can conclude that styrofoam cup is likely to float in water.

water and alcohols have similar properties because water molecules contain hydroxyl groups that can form hydrogen bonds with other water molecules and with alcohol molecules, and likewise alcohol molecules can form hydrogen bonds with other alcohol molecules as well as with water.
