  1. LZ T he variation of the vapor pressure of the liquid and solid forms of a pure substance near the triple point are given by In(Psolia/Pa) -8750(KT) +34.143 and In(Piquid/Pa) -4053(K/T) +21.10 The temperature and pressure at the triple point respectively ar. 18 Estimate the pressure necessary to melt water at -10 C if the molar volume of liquid water is 18.01 mL and the molar volume of ice is 19.64 mL. S for the process is +22.04 J/K and you can that these values remain relatively constant with temperature. You vill need this conversion factor: 1 L bar 100 J /2 The Temperature dependence of vapour pressure of solid A can be represented by log P 10- (1800 T) and that of liquid A is represented og P 8-(1400/T) . The temperature of triple point of A is (a) 200 K (b) 300 K (c) 400 K (d) 500 K CSIR JRF CHEMICAL SCIENCE
