Question

A short activity/ experiment on patilcles of matter attract with each other.

Answer 1

There are some forces of attraction between them prices of matter which bind them together. This forceof attraction between them particles of them same substance is known as cohesion. Cohesion is different in different kinds of matter. This can be explained as follows :If we take a piece of chalk, a cube ofice and an iron nail, and beat them with a hammer, we will find that it is very easy to break the piece of chalkinto smaller pieces, it requires more force to break a cube of ice, whereasthe iron nail does not break at all even with a large force. This shows that the force of attraction between them particles of chalk is quite weak, the force of attraction between the particles of ice is a bit stronger whereas the force of attraction between the particles of iron nail is very, very strong.In general, the force of attraction ismaximum between the particles of solids and minimum in the particles of gaseous matter.
