It would shrink (according to Charles's Law).
The air molecules inside the balloon will heat up and move faster, increasing the pressure inside the balloon. This will cause the balloon to expand and grow in size.
That would depend on whether the balloon was empty, full of air or full of water and as you have not told us which we can not help you. When asking questions please make them specific if you want us to help.
When you leave a balloon in the freezer, the air inside it will cool and contract, causing the balloon to shrink in size. This happens because the volume of gases decreases when they are cooled, causing the balloon to deflate.
When you place a balloon in a freezer, the air inside the balloon cools down and contracts. This causes the balloon to shrink in size. If the balloon is made of a material that can withstand the cold temperature, it will return to its original size when it warms up.
The cold temperature in the freezer will cause the air molecules inside the balloon to contract, making the balloon shrink in size. If the balloon gets cold enough, the rubber may become brittle and more prone to popping.
It would shrink (according to Charles's Law).
When the air inside a balloon cools, it will also contract, therefore the balloon will partially deflate.
If you let the air out of a balloon, it will deflate and decrease in size as the pressure inside the balloon equalizes with the external pressure.
Lowering the temperature will cause the helium gas particles inside the balloon to slow down and come closer together, resulting in a decrease in pressure. This can cause the balloon to deflate or shrink in size as the gas contracts.
Balloons shrink in the freezer because the cold temperature causes the air inside the balloon to contract, decreasing its volume. This contraction reduces the pressure inside the balloon, leading to a decrease in size.
When a balloon is placed in hot water, the air particles inside the balloon gain energy and move more rapidly, causing them to exert more pressure on the walls of the balloon. This increase in pressure leads to the balloon expanding in size as it tries to accommodate the higher pressure from the heated air molecules.
When a balloon filled with helium or CO2 is placed in the refrigerator, the gas inside the balloon will contract and become denser due to the lower temperature. This will cause the balloon to deflate slightly or shrink in size. Once the balloon is removed from the refrigerator and returns to room temperature, the gas will expand again and the balloon will regain its original size.
