1. Inflating balloons is a reversible change as once the air escapes out, the balloon comes back to its original shape and size. Hence, the change caused by inflating a balloon can be undone.
2. Harvesting crops is an irreversible change as once the crops are harvested they cannot be planted back to grow.
