Puberty.
Hopefully your body has finished to change (after puberty) at the age of eighteen. Look puberty for more, I guess
Yes, one can say that. Puberty is indeed the biggest change.
Puberty goes on until age 18-20 and does not grow after puberty. It will change because of age but not grow.
It is a chemical change as it releases gases into the air.
The testosterone produced in the testicles are what cause the voice to change during puberty.
