So what kind of change is “iron rusting” Or when a leaf turns from green to red?
What’s going on when you grind a rock to dust Or when you’re growing hair on your head?
What kind of change is “paper burning” Or when you hammer metal into foil?
What happens when you put an alka seltzer tablet on your tongue Or when you make a pot of water boil?
