because the helium expands in the balloon in order to change shape

it is a physical change because u can inflate it and deflate it
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.
an inflated because it takes up more room than a deflated one It depends on how you define the basketball. If you define it as just the rubber, then the mass does not change when it is inflated. If you consider the air inside the ball to be part of the ball then adding more air adds more mass. Mass is "stuff". Air has mass because air is stuff.
Inflating a tire with air is a physical change because it is not changing the tire chemically. It is only changing the physical appearance of the tire.
physical change. the rubber is still rubber and the air is still air, so NO chemical change has occured
A balloon is filled with helium. Athough, it can be a chemical and physical change. For example you can take the helium out of the balloon, but you cant put it back in it now that its already in the air.
Balloons can be twisted into shapes because of particles of gas can be compressed.
