Chemical Engineering Thermodynamics (MCQs)

At triple point (for one component system), vapour pressure of solid as compared to that of liquid will be

  • A. More
  • B. Less
  • C. Same
  • D. More or less ; depending on the system
Answer: Option C.

At triple point since liquid solid and gas coexist at equilibrium (thermodynamic equilibrium) so, pressure should be same we can say the vapor pressure exhibited by liquid and solid is same.
