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.
Explanation: 
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.
