Amy filled a balloon with air. She tightly tied the balloon so no air could get in or out. She kept the balloon in a warm room. An hour later she put the balloon in a cold freezer. When she took the balloon out 30 minutes later, it was still tied tightly shut. No air escaped from the balloon; however, the balloon had shrunk. Amy wondered if the mass of the balloon (including the air inside it) also changed. Mark the answer that best matches your thinking.
A. The mass of the warm balloon is less than the mass of the cold balloon
B. The mass of the warm balloon is greater than the mass of the cold balloon
C. The mass of the warm balloon is the same as the mass of the cold balloon
