MCQ
It is possible for a substance to coexist in all three phases in equilibrium, when the substance is at
- ABoyle temperature
- BCritical temperature
- ✓Triple point
- DDew point
✓
Answer
Correct option: C.
Triple point
c
Triple point of a substance can be defined as the temperature and pressure at which the three phases (gas, liquid, and solid) of that substance coexist in thermodynamic equilibrium. For eg. triple point of pure water occurs at temperature of $273.16 \; K$ and pressure of $611.2 \; Pa$.
