Sublimation

Published by . Filed under Chemistry, Gases, Physics, Scientific Terms. Total of no comments in the discussion.

Sublimation refers to the process wherein solid object directly transforms into gaseous state without passing liquefaction. There are many substances that are known to undergo this process such as the element iodine. Under extreme temperatures, iodine is converted into a gaseous state without melting first. This process explains the presence of icy cap rings and […]
