Textbook Problem

Identify the following as either physical changes or chemical changes.

  1. (a) Diy ice (solid CO2) sublimes (converts directly from solid to gaseous CO2).
  2. (b) Mercury's density decreases as the temperature increases.
  3. (c) Energy is given off as heat when natural gas (mostly methane, CH4) burns.
  4. (d) NaCI dissolves in water

(a)

Interpretation Introduction

Interpretation:

The given process should be identified as physical or chemical change.

Concept introduction:

Physical change:

A change in which the substance retains in form or state without altering in composition.  It is temporary and easily reversible.

Chemical change:

A change in which the substance loses its identity and produces one or more new substances by change in its composition.  It is permanent and not easily reversible.

Explanation

Sublimation of CO2: The process in which sublimation undergoes is a physical change because only the su
