1. A liquid sample of Ag has a volume of 1mm3 and the temperature is 1000K. The atomic volume of liquid Ag is 1.91029m3,SL is 0.192J/m2,Tm=1234K and the latent heat for melting is 83.02104kJ/m3. (10 points each.) (a) What is the critical radius? (b) estimate the number of crystal-like, spherical clusters containing 30 atoms (c) What volume of liquid silver is likely to contain one cluster of 40 atoms
