WebThe equilibrium vapor pressure is an indication of a liquid's thermodynamic tendency to evaporate. It relates to the balance of particles escaping from the liquid (or solid) in equilibrium with those in a coexisting vapor phase. A substance with a high vapor pressure at normal temperatures is often referred to as volatile.

WebLines ab, cd, and ef (tie lines) connect equilibrium compositions for each phase. The tie line is the line that describes the exact composition of the liquid phases in equilibrium for a given temperature and pressure. At the plait point, the tie lines intersect, and the length of the tie line approaches zero. WebPhase changes among the various phases of matter depend on temperature and pressure. The existence of the three phases with respect to pressure and temperature can be described in a phase diagram. Two phases coexist (i.e., they are in thermal equilibrium) at a set of pressures and temperatures. graphic drivers up to date
