Triple point can be defined as:
the condition of temperature and pressure under which the gaseous, liquid and solid phases of a substance can exist in equilibrium
The correct answer is the condition of temperature and pressure under which the gaseous, liquid and solid phases of a substance can exist in equilibrium.
A phase diagram visually represents the conditions of temperature and pressure under which different phases are stable. The lines on the phase diagram represent conditions where two phases are in equilibrium (e.g., melting curve, vaporization curve, sublimation curve). The triple point is the intersection of these three equilibrium curves. Understanding the triple point helps in predicting the phase of a substance under various conditions and is crucial in fields like thermodynamics, materials science, and atmospheric science.
