Problem 77P

Scenes A and B depict changes in matter at the atomic scale:

(a) Which show(s) a physical change?

(b) Which show(s) a chemical change?

(c) Which result(s) in different physical properties?

(d) Which result(s) in different chemical properties?

(e) Which result(s) in a change in state?

                                                                Step by Step Solution

Step 1 of 5

Physical change: A change in which the substance retains its identity and changes in form or state without altering in composition. It is reversible.

Chemical change: A change in which the substance loses its identity and produces one or more new substances by change in its composition. And it is reversible.

(a)

Scene A represents the physical change. Here, the substance changes from one phase to another phase.  That is from solid state to gaseous state.
