Explanation:
the glowing of bulb
an electric heater or a bulb glows when it is switched on .but the glow vanishes as it is switched off. so the change is reversible.
The expansion of a substance
on being heated,a substance expands but on being cooled, it contracts. also ,no new substances are formed.
changes in state of matter
change in state of matter is reversible. And also that the kind of matter remains the same in any change in state of matter.so this is reversible
sublimation
a solid like ammonium chloride, naphthalene, camphor or iodine directly forms vapours ,without melting. and when cooled, the vapours are directly converted into the solid. thus, the change is reversible.
the dissolving of a substance in a liquid
the substance that dissolves is called the solute and the liquid in which the substance dissolves is called solvent. thus, a solute dissolves in a solvent to form a solution.
