Solution for your first query,
When salt is added to water and stirred, salt particles disapper and we get clear salt solution.
This is because, when we add salt to the water and stirred to dissolve, the particles of salt separate out and enter the empty spaces between the particles.
That means, particles of matter have empty spaces between them.
