Chemistry - Real Gas Question with Solution | TestHub
Select the correct statement(s) on the basis of curve given for a substance A, during the transition between liquid and gaseous state :
Options:(select one or more)
Answer:
Solution:
Explain the question :
Select correct statements about substance A on a P–V phase diagram Concept :
isotherms and critical point on P – V diagram
Solution :
At point E , the substance is a supercritical fluid because T > Tc and P > Pe Points to the right of the saturation curve (like point D) represent the gaseous state (low pressure, high volume).
Points to the left of the saturation curve (like point C) represent the liquid state (high pressure, low volume).
The flat region of the isotherms (like point B) represents the liquid-vapor equilibrium where both phases coexist at constant pressure (vapor pressure).
