Chemical Thermodynamics
Extensive and Intensive Properties and State Functions
Thermodynamic properties (macroscopic system)
→ Intensive property
→ Extensive property
Intensive property :
Intensive property does not depend on nature, mass of the substance.
ex : P, T, Density, Viscosity, surface tension, refractive index, dipole moment, dielectric constant, concentration, pH, boiling point, molar volume.
Extensive property :
Extensive property depends on the mass of the substance on division substance values of their properties change.
Ex : Mass, volume, internal energy (V), Enthalpy (H), Entropy (S), Gibbs energy.
Heat : The energy transferred from system to surroundings on account of the temperature difference.
q = msΔT (s = specific heat
m = mass of the substance
ΔT = change in T)
Energy absorbed by the system is +ve
Energy liberated by the system is −ve.
