    Study Notes

    Main Source of Energy

    • The primary source of the world's energy is the Sun, as it provides solar energy necessary for photosynthesis and other processes.

    Low Melting Solids

    • Low melting solids include substances that have lower melting points, making them useful in various applications. Specific examples are not provided.

    Hydrocarbons Characteristics

    • Hydrocarbons are organic compounds comprised solely of hydrogen and carbon.
    • They are typically colorless and do not mix well with water due to their hydrophobic nature.

    Gaseous Hydrocarbons

    • Common examples of gaseous hydrocarbons include methane, ethane, and propane. These compounds exist in a gaseous state at room temperature.

    Raw-Material Source for Organic Chemicals

    • Oil and natural gas serve as the dominant raw-material source for the production of various organic commodity chemicals like solvents and polymers.
