Answer is: Particles are farther apart in gases so Substance B is a gas.
For example, nitrogen molecules have weakest intermolecular bonds in gas phase and move fast and without order.
Cooling is change from gas to solids. In solid state (for example ice) movement of molecules is more slow than movement of molecules in the gas (for example water vapor).
The process by which a solid changes directly to a gas without first becoming a liquid is called c. sublimation.
Sublimation is an endothermic process. For example dry ice (carbon(IV) oxide in solid state) is used because of sublimation in nightclubs, fog machines, at theaters, haunted house attractions.

Explanation:
The term suspension means mixing of small and light particles together which are not dissolved in a fluid.
Therefore, clay, slit, and sand would be carried by suspension as they have small particles as compared to small pebbles and large rocks.
In a rock, there might be substance which are soluble in water. These soluble substances are therefore, continuously removed from the rock by the action of water.
Hence, holes will appear in the rock leading to rills and rough surface. Ultimately, the rock will either decompose or fall into pieces. On acidification of water by organic and inorganic solvents, the dissolution of rock increases.
Thus, it is concluded that in solution, rocks are dissolved by salts and acids.
