Hey Mate
Here is your answer
Before classifying them into physical and chemical changes we must know the definition of physical and chemical change which is :
PHYSICAL CHANGE : A change in which only the physical properties such as size , shape etc change and there is no change in the chemical properties, this change is called the physical change.
CHEMICAL CHANGE : A change in which both the chemical and physical properties change , this is called the chemical change.
a). Evaporation of petrol =≥ Physical change
b) Burning of LPG =≥ Chemical change
c) Heating of iron rod to red hot =≥ Physical change
d) Curdling of milk =≥ Chemical change
e) Sublimation of solid ammonium chloride =≥ Physical change
Hope it helps
Cheers!!
