Question

Give each two example of temporary physical change and temporary chemical change

Answer 1

Answer:

example of temporary physical change.

1) conversion of water to ice and ice to water

2) round ball change its shape to oval when hit by a cricket bat.

since in chemical changes no new substance is formed chemical changes are permanent and are irreversible. in some specific conditions the change become reversed

like when a very intense heat is given to a diamond it can change its form from diamond to coal due to changes in chemical bond.

but generally chemical changes are irreversible.
