Answer:
Physical and Chemical Changes
We see ice melting into water, water boiling to vapours and vapours precipitating into the water droplets on cooling. These are some of the examples of Physical Changes since the transition is in the Physical Properties of Water. Substances in Nature undergo various types of changes. The changes that they can undergo are widely classified into two categories viz. Physical and Chemical Changes.
Examples of Physical Change
Breaking/Crushing of any Object
Expansion of Metal on Heating
Dissolving Sugar or Salt (Solute) in Water (Solvent) (as a result, a solution is formed)
Solidification of Molten Metal on Cooling
Shredding Paper.
Examples of Chemical Change
Rusting of Iron (Read)
Souring of Milk
Ripening of Fruits
Digestion of Food
Bursting of Crackers
