Question

the escaping tendency of a substance from one state to another is called​

Answer 1

Answer:

Lewis, is the tendency of a substance to leave its thermodynamic state by either a physical or a chemical process. ... The part played by the molal Gibbs energy in the case of ideal gases induces the introduction of the chemical potential in order to play this part in every kind of system.

Answer 2

The escaping tendency of material from one state to another is called fugacity.

• Fugacity is a measure of the propensity of an ingredient of a liquid mixture to escape, or vaporize, from the mixture. The composition of the vapour form of the mixture, above the liquid, is not similar to that of the liquid mixture; it is abundant in the molecules of that ingredient that possesses a considerable tendency to escape from the liquid stage.
• The fugacity of an ingredient in a mixture is almost the pressure that it puts out in the vapour stage when in equilibrium with the liquid mixture.
