Question

A diver is able to cut through water in a swimming pool. Which property of matter does this observation show.

Answer 1

Hint: This happens due to special properties exhibited by water. Properties that will be observed are such as space between the particle of matter, interparticle force of attraction between particle and the liquid.

Complete step by step solution:
From your chemistry lessons you have learned about the properties of water as a matter. Water can exist in all the three states of matter like they can exist as an ice in solid state, water in liquid state and in the form of vapour in gaseous state.
Water have some properties such as,
- They have large intermolecular space in liquid form, in solid form the intermolecular space is not present.
- Interparticle force of attraction is less in liquid state as compared to solid state.
- the density of water is more in liquid state and not in solid state, etc
In this question we are asked about the properties of matter through which diver can cut the water during swimming, here water is in liquid state and it shows some characteristics which able the diver to cut the water,
The properties of matter that are observed here are,
- This phenomena shows that the matter particle possesses some space between them, there is presence of intermolecular space between the liquid particles and due to this space diver is able to pass through the water.
- We know that the intermolecular or interparticle force of attraction in liquid state is less as comparison to solid state and in this case also the intermolecular force of attraction between the particle of liquid is less and thus the force applied by the diver is more than the force of attraction between the liquid particle hence, diver is capable of overcoming these force of attraction.

Note: The intermolecular force and density of gas is very much less than solid and liquid. The space and intermolecular force of attraction in solid ice will be large, so the diver will not be able to cut the ice. Due to the space between the particles they are able to move from one place to another in this way they accommodate the body of the diver.
