Answer:
Boiling point
Density
Smooth surface
Explanation:
Physical change: It is that process in which no chemical reaction takes place.
It is a change in physical state or properties of matter without accompanying change in its chemical composition.
Chemical change: It is that reaction in which chemical reaction takes place.
Chemical composition of matters change.
Physical property: Density, boiling point without changing the physical state can be observed.It is often referred as observable.It is characteristics of system or matters.It includes color, odor, solubility, density etc.
A.Rusting: Chemical property by definition of chemical property.
B.Boiling point ::Physical property by definition of physical property.
C. Density: It is a physical property by definition of physical property.
D.Flammability:Chemical property by definition of chemical property.
E.Smooth surface:It is a physical property by definition of physical property.
