Potassium permanganate changes from solid to a gas when heated.Identify the name of this process.

The process by which potassium permanganate transitions directly from a solid to a gas upon heating is known as sublimation. Sublimation is a physical process where a substance moves from a solid state to a gaseous state without going through the liquid phase. This occurs because the molecules in the solid gain enough energy (due to heat) to overcome the attractive forces that hold them in the solid form, allowing them to disperse as a gas.

Potassium permanganate, like some other solids, can undergo sublimation when heated to a certain temperature. This property is particularly important in various applications, such as analytical chemistry and some industrial processes. Understanding sublimation is crucial for handling and storing potassium permanganate safely, as it can release gas that may be hazardous in certain concentrations.
