Question

Sublimation of ammonium chloride is a physical changes. Why?
​

Answer 1

Answer:

The solid form is converted into gas.

Explanation:

So, in this reaction when the ammonium chloride or solution of ammonium chloride is strongly heated above the temperature of 340∘C, the white solid ammonium chloride is converted into two gases ammonia and hydrogen chloride. Since the solid form is converted into gas, hence it is a physical change.
