Dry ice is frozen carbon dioxide. Suppose you have a piece of dry ice with a mass of 200 grams (a little less than half a pound) which you place into a large deflated bag, which you seal. You then let heat flow into it to turn all the dry ice into gas at a temperature of 20°C. What volume will the bag have expanded to?
A scuba diver 18 m below the surface of a lake breathes out, releasing bubbles into the water. How much do the bubbles expand on their way up? Specifically, for a given bubble, what is the ratio of its volume as it reaches the surface to its volume down where it was created?
