If we increase the pressure on a substance (which is at its triple point), then the triple point __________________?
Correct answer: C. Remains unchanged
- A. Increases
- B. Decreases
- C. Remains unchanged
- D. May increase or decrease; depends on the substance
Explanation
For a pure substance, the triple point is a fixed combination of temperature and pressure at which all three phases coexist. Increasing the pressure moves the system away from that invariant point rather than changing the triple point itself.
