Ice is a solid substance. When we heat ice, it melts to form liquid water. A change from solid to liquid takes place during the melting of ice. If we cool the water from ice to water, by heating, has been reversed by cooling.Thus, the melting of ice (to form water) is a reversible change.
Heat
Ice ————————————-> Water
(Solid) <————————————- (liquid)
Cool
Examples of reversible changes are:
Melting of ice.
Boiling of water.
Melting of wax.
Stretching of a rubber band.
Stretching of a spring.
Inflation of a ballon.
Ironing of clothes.
Folding of paper.
Rolling a chapati(roti) from dough.
Dissolving salt in water.
Dissolving sugar in water.
Knitting of sweater (woollen yarn to knitted sweater).
Melting of ice candy.
Melting of ice cream (solid ice cream to molten ice cream).
Drying of clothes (wet clothes to dry clothes)
Heating of milk (cold milk to hot milk)
Expansion of metals on heating.
Straight wire to coiled wire.
Melting of coal tar.
Folding of dress (shirts etc)
Moulding of wet clay into pot on potter’s wheel and
Softening of iron on heating to red hot stage.
When we boil water by heating, then it changes into steam. Now, if we cool the steam, then water is formed again. So, the changing of water into steam has been reversed by cooling. Thus, the boiling of water (or evaporation of water) is a reversible change.
