Physical properties and physical changes has to be identified in the given statement. “The camp nurse measured the temperature of the injured camper and ignited a propane burner; when the water began to boil, some of the water vapor condensed on the cold window.” 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. In matter, changes are familiar and common occurrences. Similar to the properties of matter, changes in matter can also be classified as physical change and chemical change. Process in which, the physical appearance of the substance changes but not the chemical composition is known as physical change. Some of the examples are melting, freezing, evaporation etc. Process in which, the chemical composition of the substance changes is known as chemical change. All chemical reactions are examples of chemical change because the composition changes.

Interpretation Introduction

Interpretation:

Physical properties and physical changes has to be identified in the given statement.

“The camp nurse measured the temperature of the injured camper and ignited a propane burner; when the water began to boil, some of the water vapor condensed on the cold window.”

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.

In matter, changes are familiar and common occurrences. Similar to the properties of matter, changes in matter can also be classified as physical change and chemical change.
