season. It is noticed that the volume of the bag of potato chips has increased upon its arrival in Lake Tahoe. What external con-ditions would most likely cause the volume increase? 23. Boyle's law can be represented graphically in several ways. Which of the following plots does not correctly represent Boyle's law (assuming constant T and n)? Explain. P v liP lIV 24. As weather balloons rise from the earth's surface, the pressure of the atmosphere becomes less, tending to cause the volume of the balloons to expand. However, the temperature is much lower in the upper atmosphere than at sea level. Would this tempera-ture effect tend to make such a balloon expand or contract? Weather balloons do, in fact, expand as they rise. What does this tell you? 25. Which noble gas has the smallest density at STP? Explain. 26. Consider two different containers, each filled with 2 moles of Ne(g). One of the containers is rigid and has constant volume. The other container is flexible (like a balloon) and is capable of changing its volume to keep the external pressure and internal pressure equal to each other. If you raise the temperature
