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.
