Introduction to Gases

Overview

• What is a Gas?
  • Gases are one of the four fundamental states of matter, consisting of particles that have neither a defined volume nor shape.
  • Particles in a gas move freely and are well separated with no regular arrangement.
• Importance of Studying Gases
  • Understanding gases is crucial for explaining natural phenomena and for practical applications in industries like chemical manufacturing, energy production, and environmental science.

Characteristics of Gases

• Gases expand to fill their containers.
• They exert pressure on the walls of a container.
• Gases have low densities compared to solids and liquids.
• They are compressible, meaning they can be compacted into a smaller volume.

Gases on the Periodic Table

• Many elements exist as gases at room temperature, including noble gases and others like oxygen, nitrogen, and hydrogen.

Molecular Gases

• Molecular gases are composed of two or more atoms bonded together.
• These include diatomic molecules such as O2, N2, and H2.
