Chapter 1, Problem 1.52QP

(a)

Interpretation Introduction

Interpretation:

Evaporation of a puddle of water has to be labelled as either a physical change or a chemical reaction.

Concept Introduction:

Physical change:

A change in which no new substances are formed is said to be physical change.  It affects the chemical substance but not its composition.

Chemical reaction:

It is a process that involves rearrangement of the molecular or ionic structure of a substance.  In this, one or more chemicals reacts and forms other chemical compounds.

(b)

Interpretation Introduction

Interpretation:

Digestion of food has to be labelled as either a physical change or a chemical reaction.

Concept Introduction:

Refer to part (a).

(c)

Interpretation Introduction

Interpretation:

Burning of wood has to be labelled as either a physical change or a chemical reaction.

Concept Introduction:

Refer to part (a).
