Question

b. An inflated balloon was kept in a refrigerator. After sometime, it was observed that the balloon
started to shrink Why does the balloon shrink?
c. You can smell freshly baked cake from a distance. Why?​

Answer 1

Answer:

b) The frozen balloon shrank because the average kinetic energy of the gas molecules in a balloon decreases when the temperature decreases. This makes the molecules move more slowly and have less frequent and weaker collisions with the inside wall of the balloon, which causes the balloon to shrink a little.

c)As the smell of cake is in gaseous form, diffusion is more in gaseous state.
