Question

You accidentally dropped your favorite toy and broke it, this is a change you did not want. Can this change be reversed?

Answer 1

Chemical change:

• A chemical change is permanent and irreversible in nature. It alters the chemical properties of the substance.

Physical change:

• A physical change does not alter the composition of the substance and is reversible in nature

Breaking of the toy:

• The breaking of the toy cannot be reversed.
• The breaking of the toy is an irreversible change.
• Despite the fact that this is an irreversible change, the toy's composition was unaffected.
• This is a physical change. A physical change is a transient, reversible change that affects only a substance's physical properties without changing its chemical composition.
• A chemical change, which is an irreversible and difficult transition, occurs when the identity of a material is altered to produce one or more new compounds.
