p=p(A)^(0)x(A) 32=40xxx(A)or x(A)=0.8]The vapour pressure of a certain pure liquid A at 298 K is 40 mbar. When a solution of B is prepared in A at the same temperature, the vapour pressure is found to be 32 mbar. The mole fraction of A in the solution

Thus, this maximum possible evaporation rate m˙H per unit surface would be given by Hertz’s original expression(3)m˙H=PM2πRTwhere R is the universal gas constant, M is the molecular mass; T is the absolute temperature of the liquid and P the vapour pressure at such temperature. The...
10. Indeed, the dependence of viscosity on the identity of the chemical compound mirrors that of vapour pressure, i.e. a decrease in vapour pressure corresponds to an increase in viscosity, an observation that has been verified by some of the predictive tools described earlier...
Phase-change materials exhibit fast and reversible transitions between an amorphous and a crystalline state at high temperature. The two states display resistivity contrast, which is exploited in phase-change memory devices. The technologically most impo
Th is method was recently extended to allow the growth of III-V and II-VI semiconductors from volatile organic precursors [11]. Here, a high vapour pressure compound (typically a metal halide or a metallorganic) of each respective metal is carried independently, via a carrier gas, to a ...
