Which Statement Describes an Intensive Property of Matter?

When it comes to matter, there are several properties that scientists use to describe its characteristics. In this article, we will explore one of the most important concepts in matter: intensive properties. But before we dive into the details, let’s define what intensive properties are.

What is an Intensive Property?

An intensive property is a physical property of a system that does not depend on the amount or size of the system. In other words, intensive properties are properties that remain constant even if the amount of matter is increased or decreased. This is in contrast to extensive properties, which do depend on the amount or size of the system.

Types of Intensive Properties

There are several types of intensive properties, including:

  • Temperature (T): The temperature of a system is an intensive property that remains constant even if the amount of matter is increased or decreased. For example, the temperature of a cup of hot coffee is the same whether it is half full or full.
  • Pressure (P): The pressure of a system is also an intensive property that remains constant even if the amount of matter is increased or decreased. For example, the pressure of a gas is the same whether it is in a small container or a large container.
  • Concentration (c): The concentration of a solution is an intensive property that remains constant even if the amount of matter is increased or decreased. For example, the concentration of a salt solution is the same whether it is in a small bottle or a large bottle.
  • Density (ρ): The density of a substance is an intensive property that remains constant even if the amount of matter is increased or decreased. For example, the density of a metal is the same whether it is in a small piece or a large piece.

Examples of Intensive Properties

Here are some examples of intensive properties:

  • Color: The color of a substance is an intensive property that remains constant even if the amount of matter is increased or decreased.
  • Odor: The odor of a substance is an intensive property that remains constant even if the amount of matter is increased or decreased.
  • Texture: The texture of a substance is an intensive property that remains constant even if the amount of matter is increased or decreased.

Which Statement Describes an Intensive Property of Matter?

So, which statement describes an intensive property of matter?

  • The amount of matter in a system affects its intensive properties. FALSE This statement is incorrect because intensive properties do not depend on the amount of matter in a system.
  • The size of a system affects its intensive properties. FALSE This statement is incorrect because intensive properties do not depend on the size of a system.
  • Intensive properties are characteristics of a system that remain constant even if the amount or size of the system is changed. TRUE This statement is correct because intensive properties do not depend on the amount or size of the system.
  • Intensive properties are characteristics of a system that change when the amount or size of the system is changed. FALSE This statement is incorrect because intensive properties do not change when the amount or size of the system is changed.

Conclusion

In conclusion, intensive properties are physical properties of a system that do not depend on the amount or size of the system. Examples of intensive properties include temperature, pressure, concentration, and density. These properties are characteristics of a system that remain constant even if the amount or size of the system is changed.
