Answer:
Step-by-step explanation:
When a balloon is placed in ice, the air inside the balloon cools down and its volume decreases. This is due to the fact that gases tend to contract when they are cooled, as the molecules slow down and move closer together. As the air inside the balloon contracts, the balloon will also appear to shrink in size.
When a balloon is heated, the air inside the balloon expands and its volume increases. This is due to the fact that gases tend to expand when they are heated, as the molecules move faster and spread out. As the air inside the balloon expands, the balloon will also appear to grow in size. If the balloon is heated too much, it may burst due to the pressure inside exceeding its elastic limit.
