Chemical.....
When silver nitrate is added to water, it undergoes a physical change as it dissolves in the water. No new substances are formed during this process, so it is considered a physical change rather than a chemical change.
No, heating sodium chloride is a physical change rather than a chemical change. When heated, sodium chloride simply changes physical state from a solid to a liquid (molten form) without any change in its chemical composition.
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 potassium bicarbonate is a chemical change because it causes a decomposition reaction. This results in the formation of new substances (potassium carbonate, water, and carbon dioxide) that have different chemical properties than the original compound.
anytime any elements/mixtures are placed together it is a chemical change... a physical change is if the silver nitrate is by itself and changed it physical appearance but is the same element (like if a human changes there clothes)
Heating is a physical change.
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.

CHEMICAL:)
It is a physical change (sublimation).
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.
This is a chemical change because a new compound, potassium nitrate, is formed through a chemical reaction between the potassium iodide and lead nitrate. Physical changes do not involve the formation of new substances.
