    Study Notes

    Types of Energy

    • Potential Energy: Stored energy derived from an object’s position or structure, such as gravitational energy or elastic energy.
    • Chemical Energy: Form of potential energy stored in chemical bonds within molecules.

    Stability and Potential Energy

    • Higher stability in an object often correlates with lower potential energy, while higher potential energy indicates less stability.

    Determinants of Molecular Potential Energy

    • The potential energy in a molecule is mainly determined by the arrangement of atoms and the types of bonds present.

    Kinetic Energy

    • Thermal Energy: Associated with the random movement of particles, influencing temperature and phase states of matter.

    Laws of Thermodynamics

    • First Law of Thermodynamics: States that energy cannot be created or destroyed; it can only transform from one form to another.
    • Law of Conservation of Energy: Another name for the First Law of Thermodynamics, emphasizing that total energy remains constant.

    Photosynthesis Energy Conversion

    • Chemical Energy Conversion: During photosynthesis, plants convert solar energy into chemical energy stored in glucose.

    Entropy in Energy Conversions

    • According to the Second Law of Thermodynamics, the level of entropy in the universe increases during energy conversions, indicating a trend towards disorder.

    Free Energy in Cells

    • Gibbs Free Energy (ΔG): Represents the amount of free energy available for performing work in biological systems.

    Spontaneous Reactions

    • A chemical reaction is said to be spontaneous if ΔG is less than zero, indicating that the reaction can occur without additional energy input.
