Gallium metal melts at 29.8°C. At the melting point the density of the solid is 5-90 g/ml, and that of the liquid is 6.10 g ml. a Does solid gallium expand or contract when it is melted? contracts Explain The same amount of mass occupies space in the liquid phase than in the solid phase. 6. What is the change in volume when 6.10 mL (cm) of solid gallium is melted? Volume by mi Reference Lt 30.0°C.Calculate the change in...
A hydrometer is an instrument used to determine liquid density. A simple one is sketched in the figure below. The bulb of a syringe is squeezed and released to let the atmosphere lift a sample of the liquid of interest into a tube containing a calibrated rod of known density. The rod, of length L and average density rho_0, floats partially immersed in the liquid of density rho. A length h of the rod protrudes above the surface of the...
what is the melting point of a solution in which 3 grams of sodium chloride is added to 170 ml of water? The cryoscopic constant of water is Kf=1.86Kkgmol-1.
The solid/liquid phase transition of water near 1 atm external pressure is an important feature of our daily lives. Some relevant data concerning the transition include the density of liquid water at 273.15 K (0.999 g cm-3), the density of ice at 273.15 K (0.917 g cm-3), and the enthalpy of fusion of water at 273.15 K (6.008 kJ mol-1). (a) On a phase diagram, this transition appears as a line. Calculate the slope of this transition line near the...
