Question

Classify the following as reversible or irreversible changes

Answer 1

Answer:

my own answer:

reversible changes: reversible changes are physical changes and the changes that can be reversed by using certain physical process is called reversible changes. and only the physical properties of the object gets changed like: size and shape for example: water is cooled to form solid substance called ice. that can be again heated to form liquid substance is water.

irreversible changes: irreversible changes are the changes that cannot be reversed like the physical change , as it is probably called as chemical change. that the both chemical and physical properties of an object gets changed as like every thing in the object like shape, size, colour, chemicals etc. for example: broken pieces of glasses.
