    Study Notes

    Termoterapia and Cryotherapy

    • Termoterapia: Uses heat to treat injuries or illnesses. Often used to relieve muscle pain, improve blood flow, and promote relaxation.
    • Effects: Hemodynamic (vasodilation), neuromuscular (acceleration), metabolic (acceleration) and tissue extensibility.
    • Cryotherapy: Uses cold to reduce inflammation, relieve pain, and limit tissue damage, particularly after acute trauma.
    • Effects: Hemodynamic (vasoconstriction), neuromuscular, and metabolic.

    State Variables and Non-State Variables

    • State Variables: Describe the state of a thermodynamic system regardless of how that state was reached.
    • Examples: Temperature, pressure, volume, internal energy.
    • Non-State Variables: Depend on the path taken to reach a specific state.
    • Examples: Heat (Q), work (W).

    Intensive and Extensive Variables

    • Intensive Variables: Do not depend on the amount of matter.
    • Examples: Pressure, temperature, density
    • Extensive Variables: Depend on the amount of matter.
    • Examples: Mass, volume, number of moles, internal energy.

    Gas Laws and Thermodynamic Concepts

    • Ideal Gas Law: PV=nRT.
      • P = Pressure
      • V = Volume
      • n = Number of moles
      • R = Ideal gas constant
      • T = Temperature
    • Temperature (T): Measurement of particle motion in a system unit → Kelvin (°C)
    • Heat (Q): Thermal energy transferred between systems due to a temperature difference. (Unit: Joules, J)
    • Latent Heat (L): Energy needed to change the physical state of a substance without changing its temperature (Unit: Joules per kilogram).
    • Specific Heat (c): Amount of heat needed to raise the temperature of a unit mass of a substance by 1°C.

    Methods of Heat Transfer

    • Conduction: Heat transfer through direct contact in solids.
    • Convection: Heat transfer through the movement of fluids (liquids or gases).
    • Conversion: Transforming one form of energy (e.g., electrical or chemical) into heat.
    • Radiation: Heat transfer as electromagnetic waves (infrared).
    • Evaporation: Cooling effect when a liquid changes to a gas. Absorbs latent heat.
