1. Understanding Vapour

1.1 Definition of Vapour

Vapour is defined as the gaseous phase of a substance, particularly when it can condense back into a liquid. Unlike gases, vapours exist at a temperature below their critical temperature, meaning the substance can change back to its liquid state under certain conditions. Vapours are typically less dense than liquids and can diffuse quickly in the air.

1.2 Properties of Vapour

Understanding the properties of vapour is crucial for its applications:

  • Density: Vapour is generally less dense than its liquid counterpart.

  • Viscosity: Vapours usually have lower viscosity compared to liquids, promoting easier flow.

  • Diffusion: Vapour molecules can diffuse rapidly within the air, affecting distribution and concentration.

  • Solubility: Vapours can dissolve in other gases or liquids, making them versatile in various physiological and chemical processes.

1.3 Types of Vapour

The categorization of vapour typically divides it into three major types:

  1. Water Vapour: The gaseous state of water, prevalent in the atmosphere.

  2. Organic Vapour: Vapours emitted from organic substances, including volatile organic compounds (VOCs).

  3. Inorganic Vapour: Vapours from inorganic substances, often involving metals or minerals.

2. Major Types of Vapour

2.1 Water Vapour

2.1.1 Characteristics and Properties

Water vapour is present in the atmosphere as a significant factor affecting climate, weather, and even human health.

  • Molecular Composition: Water vapour consists of H₂O molecules that have energy and motion, causing them to escape liquid water.

  • Role in Climate: Water vapour acts as a greenhouse gas, trapping heat in the atmosphere and influencing temperature regulation.

  • Humidity: The amount of water vapour in the air directly affects humidity levels, impacting weather patterns and living conditions.

2.1.2 Applications of Water Vapour

  • Meteorology: Water vapour plays a significant role in weather forecasting, aiding in the prediction of storms, rain, and other weather phenomena.

  • Industrial Processes: Used in steam cleaning, sterilization, and as a coolant in HVAC systems.

  • Agriculture: Essential for irrigation systems and greenhouses where humidity control is crucial for crop yield.

2.2 Organic Vapour

2.2.1 Characteristics and Properties

Organic vapours refer to those generated from carbon-based compounds:

  • Composition: These can include solvents like benzene and ethanol, which are emitted particularly in industrial processes.

  • Vapor Pressure: Many organic vapours possess significant vapor pressure, allowing for rapid evaporation and widespread dispersion.

2.2.2 Applications of Organic Vapour

  • Solvents and Cleaners: Organic vapours serve as solvents for paints, varnishes, and cleaning agents, allowing efficient penetration and removal of dirt.

  • Chemical Manufacturing: Vital in producing pharmaceuticals, pesticides, and other chemical compounds.

  • Aerosol Products: Contributing to the formulation of spray paints, perfumes, and deodorants.

2.3 Inorganic Vapour

2.3.1 Characteristics and Properties

Inorganic vapours encompass a wide range of substances:

  • Examples: Common pollutants such as chlorine gas (Cl₂) and sulfur dioxide (SO₂).

  • Chemical Behavior: Often react with air or moisture to form acids or particulates, posing environmental and health risks.

2.3.2 Applications of Inorganic Vapour

  • Industrial Applications: In manufacturing processes, such as steel production and chemical synthesis.

  • Laboratory Uses: Used for etching, cleaning surfaces, or conducting experiments involving inorganic compounds.

  • Water Treatment: Used to control microbial growth in water supplies through chlorine vapour.
