At triple point (for one component system), vapour pressure of solid as compared to that of liquid will be________________?
Correct answer: C. Same
- A. More
- B. Less
- C. Same
- D. More or less; depending on the system
Explanation
At the triple point, solid, liquid and vapour coexist in equilibrium. The solid and liquid therefore have the same vapour pressure at that temperature, making option c correct.
