Textbook Question

Describe each of the following as a physical or chemical property: a. Neon is a colorless gas at room temperature.

Verified step by step guidance

Understand the difference between physical and chemical properties: Physical properties can be observed or measured without changing the substance's identity, while chemical properties describe a substance's ability to undergo a chemical change.

Identify the property in question: The statement describes neon as a colorless gas at room temperature.

Determine if the property involves a change in the substance's identity: Being colorless and gaseous at room temperature does not involve changing neon into another substance.

Recognize that the state of matter and color are physical properties: These characteristics can be observed without altering the chemical composition of neon.

Conclude that the property described is a physical property, as it pertains to the observable characteristics of neon without involving a chemical change.

Key Concepts

Here are the essential concepts you must grasp in order to answer the question correctly.

Physical Property

A physical property is a characteristic of a substance that can be observed or measured without changing its chemical identity. Examples include color, odor, boiling point, and state of matter. In the case of neon being a colorless gas at room temperature, this observation does not alter the chemical structure of neon.

Chemical Property

A chemical property describes a substance's ability to undergo a specific chemical change or reaction. This includes reactivity with other chemicals, flammability, and acidity. Unlike physical properties, chemical properties can only be observed during a chemical reaction, which is not applicable to the description of neon as a gas.

State of Matter

The state of matter refers to the distinct forms that different phases of matter take on, primarily solid, liquid, gas, and plasma. Neon, being a gas at room temperature, indicates its state of matter, which is crucial for understanding its behavior and properties in various conditions.
