MICk3Y Wrote:So in my biology class wee were discussing whether a baby gaining 10 pounds is a physical change or a chemical change. The definition of a chemical change in our books is "when the change made is irreversible". So I'm wondering, what does EP think this is?Hmmm

in my chemistry class, a Quimical Change is a change that involves modifying the chemical composition of the sustance,

but that is a physical one anyways because a baby can lose those 10 pounds...
