Increased pressure on the inside, or decreased pressure on the outside.
No, the balloon did not change size.
The shape and size of a balloon change when filled with air or water because the molecules of the substance fill the balloon and exert pressure on its walls. This pressure causes the balloon to expand and take on the shape of its contents. The volume of the balloon increases as more air or water is added, changing its size accordingly.
Because the air is coming inside the balloon.
If a balloon were completely filled with water, with no extra space, then it will change shape and/or size as the water is frozen. This is because water expands at a rate of 9% when frozen.
The mass of the balloon is independent. Atmospheric pressure will not change this because atoms are not being added or taken away from the balloon itself or its contents. The volume of the balloon will change, however, as it will expand or compress in response to the atmospheric pressure around it. The volume, therefore, is a dependent variable in this situation.
When a balloon is squeezed, the forces exerted on it cause the air inside the balloon to be compressed. This compression increases the pressure inside the balloon, leading to a change in the balloon's shape and size. If the squeezing force is too strong, it can cause the balloon to burst.
The size of the balloon does impact its lifting capacity because a larger balloon can displace more air and generate more lift. So, larger balloons generally have a greater lifting power compared to smaller ones.
the balloon's volume would decrease!!!
It increases its size in two ways: # The interior gas pushes outward harder as it warms, and # The rubber of the balloon gets softer, easier to stretch, and its surface area (and hence its contained volume) increases a bit also.
As it gets colder the air molecules move closer together and the balloon deflates.
The balloon would shrink in size as the air inside cools and contracts. This is because gases, like the air in the balloon, contract when they are cooled and expand when they are warmed.
To change your voice using a balloon, stretch a balloon and hold it near your mouth while talking or singing through it. The pitch and sound of your voice will be altered as the balloon vibrates with the sound waves passing through it. Experiment with different size balloons to achieve different effects.
