Which of the following change(s) takes place when a paper is folded into a paper plane.
Which of the following change(s) takes place when a paper is folded into a paper plane.
The correct options are
B Temporary change
D Physical change
Temporary change:- The changes that are not permanent and are there for a limited period of time are called temporary changes. In these changes, the original state of substance can be retained, i.e., they are reversible.
Physical change:- In a physical change no new substance is formed and the chemical composition of substance remains the same. There are changes in physical properties like shape, size, etc.
Making a paper plane does not change the chemical composition of the paper (physical change). Moreover, the paper that is converted to the paper plane is not a permanent change and can easily be brought back to its initial state whenever required (temporary change).
