Answer 1

The correct option is B physical change

A change in which a substance changes its physical properties like appearance, texture, colour, odour, melting points, boiling points, density, solubility, polarity etc... are called physical changes.

Physical properties can be observed or measured without changing the composition of matter. They are used to observe and describe matter.

Hence, the correct option is $\text{B}$
