Question
A sample of cyclohexane (C6H12, bp = 81 °C) is introduced into an evacuated container at 40 °C. One-third of the cyclohexane by mass is in the form of the liquid and two-thirds is in the form of the vapor. The volume of the container is then doubled, maintaining the temperature at 40 °C. What happens to the pressure as the volume is doubled?
A.
The pressure remains the same.
B.✓ Correct
The pressure decreases by 25%.
C.
The pressure decreases by 33%.
D.
The pressure decreases by a factor of two.
