Because, the alcohol molecules spreed in the inter molecular spaces between water molecules.
It is very hard to fragmentize a piece of iron with your fingers. why?
Because, the inter molecular forces between solid molecules of solid are very large.
It is easy to divide an amount of water into small droplets or cups.why?
because, the inter molecular forces between water or liquid molecules are weak and the inter molecular spaces are intermediate.
The solid substances keep their shape whatever the container shape differs , while the liquid takes the shape of its container.
because, in solid the inter molecular forces are very strong and has tiny spaces while in liquid ,the inter molecular forces are weak and has large spaces.
When you leave the perfume bottle opened you smell it all over the room.why?
