Injecting air into the ice cream creates more volume and the air part is called "overrun" and by law in California I believe there cannot be more than 50% "overun" in ice cream sold to the public. Yup, if you let ice cream melt and sit long enough and all the air bubbles are released, you will have a lot less volume of material. I believe emulsifiers are added to keep the ice cream from getting rock hard when it's frozen like the home made stuff. And, of course, it's easier to scoop.
