Density, ultrasonic velocity and viscosity of caffeine a pharmaceutically significant drug in water at four temperatures were measured. The partial molar volume ($Vo), partial molar compressibility (d,o) and the viscosity B coefficient were calculated from the experimental data. Values of QIVO and $
