Question

When a student squeezes a balloon, it changes shape. In which state of matter is the substance inside the balloon?

A. It could be either a liquid or a gas, because these states can change shape.
B. It could only be a liquid, because only liquids can change shape
C. It could only be a gas, because only gases can change shape.
D. It could not be a liquid or a solid, because neither of these states can change shape.​

Answer 1

The answer is A.
If you think about it, you have two balloons, a helium filled ballon and a water balloon. When you squeeze them, they will change shape. So yes liquid and gas changes. So you can cross out B and C. Now let’s look at D. D says it could not be a liquid or solid because neither can change. Well we just said liquid can change. But half of D is correct, solid cannot change shape. Think about a frozen water balloon. It’s ice instead of water on the inside. (I’m not sure if it’s even possible to have a frozen water balloon.) if you squeeze that ice balloon, it won’t change.
