Question

Define physical and chemical properties, provide three examples of each, discuss their reversibility, and explain the fundamental differences between them.

Answer 1

Chemical properties are related to chemical bonds of the substance while physical properties are not.

In chemical properties, chemical identity of substance changes while physical properties do not have any change.

Chemical properties predict the reaction of substance while physical properties only describe the appearance of the substance.

Step-by-step explanation:

Answer 2

Physical properties are defined as the properties which can be observed without changing its chemical composition.

For example: color, volume, and molecular weight.

Chemical properties are defined as the properties which can be observed only after changing chemical identity of the substance.

For example: reactivity, toxicity, and flammability.

The fundamental differences between physical and chemical properties are as follows:

• Chemical properties are related to chemical bonds of the substance while physical properties are not.
• In chemical properties, chemical identity of substance changes while physical properties do not have any change.
• Chemical properties predict the reaction of substance while physical properties only describe the appearance of the substance.
