Question

Name the change in inflation of the balloon

Answer 1

Answer:

The change in the inflation of a balloon is a physical change.  

When we fill air into a balloon, it expands. However, when we deflate the balloon, the air comes out, and the balloon still remains a balloon. It does not become something else.  

Physical changes may change the size and shape of an object, but they do not alter the composition of the original material. In physical changes, no new substance is formed, but in chemical changes new substances are formed. For example, the burning of paper is a chemical change. When paper is burnt, it turns to ash. You cannot ‘unburn’ it and make it paper again

Answer 2

Change in inflation of balloon is a reversible change as well as physical change.

Explanation:

• When air is blown into a balloon, its size and shape change and the balloon gets inflated.

• Now when air is filled in the balloon is allowed to escape, the balloon comes back to its original size and shape. Hence, inflating a balloon is a reversible change.

• It is a physical change as there are no chemicals involved  and the only change that happens is in its shape and size.

• Physical change is a process that changes the state of a system and no new substance is formed and the chemical composition of the substance remains the same. The only changes that happen is in its physical properties i.e. shape and its size.

• Reversible change is a process in which the original form of substance can be retained by any physical process. These are temporary changes.
