The triple point of a substance is the temperature and pressure at which of the substance exists as which of the following?What is the triple point of a substance?
Correct answer
A
Rationale
The triple point of a substance refers to the specific temperature and pressure at which the substance can exist in equilibrium as solid, liquid, and gas phases simultaneously. This unique point represents the conditions under which all three phases coexist in equilibrium, allowing for phase transitions without a change in temperature or pressure. It is a crucial concept in thermodynamics and phase diagrams, illustrating the conditions where a substance can exhibit distinct phases simultaneously.
