camphor disappears if kept in air for a few days
Answers
camphor disappears if kept in air for a few days due to sublimation.it turns into gaseous form without turning into a liquid. it turns into its gas form and is thus no longer visible to the eyes.
Answer:
"Camphor" is a "sublimatory substance" i.e., it goes through the "process of sublimation" in which a solid substance directly gets converted into its "gaseous phase" without going through its "intermediate liquid phase". Any substance is made of atom and molecules whose particles have by strong "inter molecular forces of attraction" between them. If these forces are weak, the particles can be separated easily, with small amount of energy. This happens in the case of camphor which gains this energy from the atmosphere and converts into its vapour phase.
