Question

Mr Mann cut a cucumber. Mr Mann said, you have performed a chemical change. Is he right?​

Answer 1

Nope.

Step-by-step explanation:

Chemical change is transforming the cucumber into a pickle. However, you need vinegar, so it isn't a full change.

Therefore, Mr. Mann would not be right either way, because all he did was cut a cucumber, and he should probably get some help with all this "chemical change".

Answer 2

No.

Step-by-step explanation:

The cut cucumber is still a cucumber.
