    Study Notes

    Calorimetry and Thermodynamics Quiz Study Notes

    What is Calorimetry?

    • Calorimetry is the science of measuring heat transfer between systems
    • It involves the study of heat changes in chemical reactions and physical transformations

    What is Thermodynamics?

    • Thermodynamics is the study of energy changes in systems
    • It deals with the relationships between heat, work, and energy

    Laws of Thermodynamics

    • The Zeroth Law of Thermodynamics: if two systems are in thermal equilibrium with a third system, then they are also in thermal equilibrium with each other
    • The First Law of Thermodynamics: energy cannot be created or destroyed, only converted from one form to another
    • The Second Law of Thermodynamics: the total entropy of an isolated system always increases over time

    Types of Systems

    • Open System: matter and energy can be exchanged with the surroundings
    • Closed System: energy can be exchanged with the surroundings, but matter cannot
    • Isolated System: neither matter nor energy can be exchanged with the surroundings

    Heat Transfer

    • Conduction: heat transfer through direct contact between particles
    • Convection: heat transfer through the movement of fluids
    • Radiation: heat transfer through electromagnetic waves
