Answer:
sublimation, melting, melting, sublimation
Explanation:
Melting is defined by a process when any matter being in its solid state changes its state to liquid when introduced to heat while sublimation is a process when the matter in solid state changes directly to gaseous state when introduced to heat.
therefore,
"Iodide produces fumes when heating" is sublimation.
"An iceberg turn to ocean water" is melting.
"Candle wax turns to liquid when hot" is melting.
"Fog is created from dry ice" is sublimation.
