1.	Put some glass balls into a glass tumbler up to its 5-6 cm height. Addsome salt to it. You will observe that there is no increase in the volume due to the addition of salt up to the level of glass balls. Considering the glass balls into a glass tumbler as particles of matter, which of the following statements is correct?(a) There is an attraction between the particles of matter.(b) There is space between the particles of matter.(c) There is repulsion between the particles of two matters.(d) There is neither attraction nor repulsion between the particles of matter.
Answer» $\huge\sf\underline{\underline{Answer}}$ (A) Although there is attraction between the particles of matter, but the volume increases on ADDING one matter into another only when The SPACE between the particles in negligibly small and The particles of matter to be added are bigger in size and do not occupy the empty inter PARTICLE space. (B) Correct. The salt particles occupy the space between the glass balls. The volume does not INCREASE as long as the space between the glass balls is not filled up. (c) According to VAN der Waals forces, there is an attraction between the particles of matter. (d) According to Van der Waals forces, there is an attraction between the particles of matter.

but the volume increases on ADDING one matter into another only when

(B) Correct. The salt particles occupy the space between the glass balls.

The volume does not INCREASE as long as the space between the glass

balls is not filled up.

(c) According to VAN der Waals forces, there is an attraction between the

particles of matter.

(d) According to Van der Waals forces, there is an attraction between the

particles of matter.
