Question

solids generally undergoes melting on heating. but some sokids like nepthalene goes under sublimation. why??​

Answer 1

Sublimation means when a solid changes directly into gaseous state without going into the liquid state. Naphthalene undergoes sublimation because naphthalene is highly volatile in nature and there is weak force of attraction between its molecules. As a result, it undergoes sublimation even at room temperature
