A student inflates a balloon for a party inside her house, where the temperature is 23°C. She then takes the balloon outside, where the temperature is 12°C. What most likely will happen to the balloon?

A passenger opens a resealable bag of raisins before the plane takes off from approximately sea level. He reseals the bag and leaves some air surrounding the raisins. What will the bag most likely look like when the plane is at its highest altitude?
