18. Calculate the pressure required to lower the melting point of ice by 1'C. (L=79.6 cals./gm., specific volume of water at 0.C=1.000 c.c., specific volume of ice at 0.C=1.091 c.c. and 1 atmos.=1.013 x106 dynes/cm2.). (Ans. 136.1 atmos.)(c) Calculate the change in the melting of ice at 0 'C when pressure is lowered by 3 atm How much pressure is required to increase the melting point by 2 C. Given; latent heat of fusion is 3.34 x 105 //kg and specific volumes of water and ice are 1.002 cm3 an 1.091 cm respectively
