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 water produces hydrostatic pressure
The balloon is filled with a gas.
No. (Squeeze a balloon.)
Yes
because the helium expands in the balloon in order to change shape
If the balloon is not encased or in restricted volume, then it changes its shape to accomodate that push but prutruding on the other side and the pressure remain same. However, if there is restriction for shape change, then when you push on the balloon, the volume decreases and therefore the pressure increases. A practical balloon, by the way, will behave between these two extremes. Pushing on one side and causing it to change shape definitely results in an increase in internal pressure. This is because the elasticity/tension of the rubber is the encased space.
no, bursting of balloons is a physical change as the only change that occurs that that the shape of the balloon changes . Coming out of air is not a chemical change.
Because the air is coming inside the balloon.
The balloons shape changed and went through an outward distortion. The volume of the balloon expanded as air was blown into it.
Balloons can be shaped differently because of the way they are manufactured. The shape of a balloon is determined by the mold or template used during the manufacturing process. Even though they are filled with the same air, the shape of the balloon is determined by its design and not by the air inside.
If a charged rod is brought close to a gas filled balloon, one will notice a change in shape in the balloon. In short, the charge of the rod works on the molecules of the gas within the balloon and cause the balloon to elongate.Ê
The drop in temperature will cause the atoms (or air) inside the balloon to fall in energy levels, this will result in the pressure inside the balloon dropping, and may cause the balloon to loose its shape.
