An example of a substance that does not change directly from solid to gas when heated is

NH\(_4\)Cl\((_s\))

I\(_2\)\((_s\))

CaCO\(_3\) \((_s\))

S\(_8\) \((_s\))

Explanation

NH\(_4\)Cl, I\(_2\), S\(_8\) all undergo sublimation. i.e changes from solid to gaseous substances without first changing to liquid, when heated but CaCO\(_3\) does not.
