It is a physical change (sublimation).
Heating potassium chloride crystals is a physical change because it only affects the physical state of the substance (solid to liquid) without changing its chemical composition.
Heating is a physical change.
Heating copper sulfate crystals is a physical change because it only involves a change in state from solid to liquid or gas, without altering the chemical composition of the substance. Chemical changes involve the rearrangement of atoms to form new substances with different properties.
Heating is a physical process.
Heating a frying pan is a physical change. A chemical change is when you change the chemical properties. Heating the pan is only changing the temperature of the pan not the chemical make up.

Heating a substance can result in either a physical change or a chemical change. A physical change does not alter the substance's composition, such as melting or boiling, while a chemical change leads to the formation of new substances with different properties, such as burning or baking.
Heating is a physical process but during heating some chemical reactions are possible.
This is a chemical reaction; oxygen is released.
