Thanks dear for asking. Hope this helps you...

Answer 2

Answer:

False, it changed directly from Solid to gaseous state.

Explanation:

Sublimation is the process of certain substance changed from Solid state to gaseous state. Camphor and Naphthalene are the good examples of sublimation process. Freezing is the process which directly changes from liquid to solid state, this process is occurred in the below zero temperature in water. Difference substances have their different critical temperature changed from one state to another state of the matter. Temperature determines the state of the substance.
