Is the triple point constant point?

Answer» Thanks<br>Triple point. ... In thermodynamics, the triple point of a substance is the temperature and pressure at which the three phases (gas, liquid, and solid) of that substance coexist in thermodynamic equilibrium. For example, the triple point of mercury occurs at a temperature of −38.83440 °C and a pressure of 0.2 mPa.<br>No it is not constant for evry matter<br>In thermodynamics, the triple point of a substance is the temperature and pressure at which the three phases (gas, liquid, and solid) of that substance coexist in thermodynamic equilibrium.for example, the triple point of mercury occurs at a temperature of −38.83440 °C and a pressure of 0.2 mPa.In addition to the triple point for solid, liquid, and gas phases, a triple point may involve more than one solid phase, for substances with multiple polymorphs. Helium-4 is a special case that presents a triple point involving two different fluid phases (lambda point).<br>I am trying to say ," is the triple point constant for every matter or different?<br>i dont understsnd your question
