  2. Study of densities, speeds of sound, and refractive indices in the binary liquid mixtures of toluene with some secondary and ternary alcohols at six temperatures and atmospheric pressure;

  3. Densities, refractive indices and derived properties of binary liquid mixtures of methanol with benzene and toluene at T = (293.15, 298.15, 303.15 and 308.15) K and 0.1 MPa;

  4. Prediction of excess molar volumes from refractive index data in the binary systems containing alcohols and aromatics;

  5. Prediction of excess molar volumes from refractive index data in the binary systems containing alcohols and haloaromatics;

Pjesa eksperimentale e ketyre temave do te realizohen ne Laboratorin Nr.6 te Departamentit te Fizikes. Ka mundesi te studjohen te gjitha llojet e perzierjeve te lengeta (binare, ternare, etj.) joelektrolitike perberesit e te cilave nuk bashkeveprojne ndermjet veti per te krijuar ndonje substance te ngurte. Lab.6 i ka te gjitha kushtet per pergaditjen dhe strehimin e mostrave. Laboratori posedon digistor, si dhe pajisje mbrojtese (maska, doreza, syze mbrojtese, etj.)


Laboratori posedon peshore analitike me precizitet deri 0.1mg;

Madhesite fizike te cilat mund te maten jane:

  • Densiteti (me precizitet 0.005 kg/m3)

  • Shpejtesia e zerit (me precizitet 0.5 m/s)

  • Viskoziteti kinematik (me precizitet ~0.002 mm2/s)

  • Indeski i thyerjes (me precizitet 0.0002 njesi)

  • Kendi i rrotullimit optik (per lengje te cilat shfaqin nje te tille)


Nga madhesite e matura mund te llogariten nje numer i madh i parametrave te ketyre perzierjeve, te cilat japin informacione te rendesishme per llojet e bashkeveprimeve ndermjet perberesve te perzierjeve. Madhesite e nxjerra jane p.sh. (ne anglisht):

  • Excess molar volume

  • Free volume

  • Adiabatic compressibility

  • Molar refraction

  • Intermolecular free length

  • Specific acoustic impedance

  • Internal pressure, etj.
