Question

Arrange in the order indicated for solids, liquids and gases:
(i) Decreasing order - empty space between
(ii) Increasing order - tendency to flow

• A. (i) solid, liquid, gases (ii) gases, liquids, solids
• B. (i) solid, liquids, gases (ii) solids, gases, liquids
• C. (i) gases, liquids, solids (ii) solids, liquids, gases
• D. (i) solids, gases, liquids (ii) gases, solids, liquids

Answer 1

The correct option is C (i) gases, liquids, solids (ii) solids, liquids, gases

Decreasing order - empty space between solids, liquids, and gases: Gases, Liquids, Solids

Explanation - Space between particles is directly proportional to force of attraction between them, it is minimum in gaseous state and maximum in solid state because of this reason, solids have a definite shape and volume, and can't flow. Because the particles are already packed closely together, solids can't easily be compressed.

Increasing order - tendency to flow for solids, liquids and gases: Solids, Liquids, Gases

Explanation - tendency to flow is minimum in solid due to the immovably fixed position of their particles and maximum in gas particles because of least force of attraction among them.
