Chapter 1, Problem 1.13EP

(a)

Interpretation Introduction

Interpretation:

Substance does not react with oxygen at $50°C$ is classified as physical property or chemical property has to be given.

Concept Introduction:

All kinds of matter are distinguished from one another based on their properties.  This is used for description and identification of the matter.  Two types of properties are there for matter and they are physical property and chemical property.

If a property of a matter is observed without changing the identity of the substance, then it is a physical property.  Some of the common physical properties are melting point, boiling point, color etc.  Physical state of the substance may change but not its chemical identity during determination of physical property.

Chemical property of a substance is the one that tells about the substance behavior to undergo or resist change in forming a new substance.  Chemical property of a substance is the one that changes the identity of the substance.

(b)

Interpretation Introduction

Interpretation:

Substance react explosively with oxygen at $425°C$ is classified as physical property or chemical property has to be given.

(c)

Interpretation Introduction

Interpretation:

Substance does not melt when heated to $100°C$ is classified as physical property or chemical property has to be given.

(d)

Interpretation Introduction

Interpretation:

Substance melts at temperature that exceeds $250°C$ is classified as physical property or chemical property has to be given.
