Chapter 3, Problem 8c
Indicate whether each of the following describes a gas, a liquid, or a solid:
c. Helium occupies the entire volume of a balloon.
Verified step by step guidance1
Step 1: Understand the properties of gases, liquids, and solids. Gases have no fixed shape or volume and expand to fill the container they are in. Liquids have a fixed volume but take the shape of their container. Solids have both a fixed shape and volume.
Step 2: Analyze the behavior of helium in the given scenario. The problem states that helium occupies the entire volume of a balloon.
Step 3: Relate this behavior to the properties of gases. A substance that expands to fill the entire volume of its container (in this case, the balloon) is characteristic of a gas.
Step 4: Conclude that helium in this scenario is behaving as a gas because it conforms to the property of gases by occupying the entire volume of the balloon.
Step 5: Verify your understanding by comparing this behavior to the properties of liquids and solids, which do not expand to fill the entire volume of their container.

Key Concepts
Here are the essential concepts you must grasp in order to answer the question correctly.
States of Matter
Matter exists in three primary states: solid, liquid, and gas. Solids have a fixed shape and volume, liquids have a fixed volume but take the shape of their container, and gases neither have a fixed shape nor a fixed volume, expanding to fill their container completely.

States of Matter Concept 1
Properties of Gases
Gases are characterized by their ability to expand and fill the volume of their container. This is due to the high kinetic energy of gas molecules, which allows them to move freely and spread out, resulting in low density and compressibility compared to solids and liquids.

Kinetic Molecular Theory
The Kinetic Molecular Theory explains the behavior of gases based on the motion of their particles. It posits that gas particles are in constant, random motion and that the temperature of a gas is directly related to the average kinetic energy of its particles, influencing how gases occupy space.
