    Study Notes

    Thermodynamics

    • Thermodynamics is the branch of science that deals with the change of heat energy from one form to another form.

    Thermochemistry

    • Thermochemistry is the branch of chemistry that deals with the measurement or calculation of heat absorbed or given out in a chemical reaction.

    Types of Chemical Reactions

    Exothermic Reactions

    • An exothermic reaction is a chemical reaction that releases heat energy.
    • Example: Combustion of gasoline in a car engine.

    Endothermic Reactions

    • An endothermic reaction is a chemical reaction that absorbs heat energy.
    • Example: Photosynthesis in plants.
