Physical: In pure form it is a shiny metal. It has a low density. It is malleable.
Chemical: In pure form it corrodes easily upon exposure to air. It reacts violently with water to form potassium hydroxide and release hydrogen gas.

Sleeping involve some chemical reactions and physical phenomenons but I suppose that it is exaggerate to consider sleep as a chemical/physical change.
Physical, because it doesn't change chemical make up it just changes the appearance and texture
In a physical change, the chemical composition of the substance remains the same, but some physical properties like shape, size, or state may change. This means that the substance can be reversed back to its original state without undergoing a chemical reaction.
It can be either. Some exothermic processes, such as combustion, are chemical changes while others, such as condensation, are physical.
CHEMICAL:)
Physical ------------------- It is a chemical change because some compounds from bread are thermally decomposed. The reaction is not reversible.

Physical Property are those that can be observed or measured without affecting the composition of the sample. Density, hardness, viscosity, malleability, solubility, melting temperature, and boiling temperature are some examples of physical property.
Chemical, physical is generealy changes between the states of matter, although those are not the only physical changes
It's a physical change why are some people f$#@%ing stupid and saying a chemical change??
