If we take a piece of chalk, a cube of ice and an iron nail, and beat them with a hammer, we will find that it is very easy to break the piece of chalk into smaller particles, it requires more force to break a cube of ice, whereas the iron nail does not break at all even with a large force.
CONCLUSION :
This shows that the force of attraction between the 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.

ektapasrichaosq70r:
but this does not give the answer of activity to show forces of attraction between particles of 'water'
pls answer again
Ok
Drop a crystal of copper sulphate or potassium permanganate into a glass of hot water and another containing cold water. Do not stir the solution. Allow the crystals to settle at the bottom.
What do you observe just above the solid crystal in the glass?
What happens as time passes?
What does this suggest about the particles of solid and liquid?
Does the rate of mixing change with temperature? Why and how?
