Explanation:
Latent Heat definition: Substance change its phases like Solid, Liquid & Gases.
In this process when a substance or body melts or evaporates, some heat is released or absorbed in the form of thermal energy during constant temperature is called Latent Heat.
Order of Phase transitions changes: There are many orders of phase changes.
latent heat
A Phase diagram is a graph between Temperature (T) and pressure (P) in between equilibrium state of any two phases of a substance.
The First Order of phase change transition: Where the heat is either absorbed or released.
In other words, we can say that where a system either released or absorbed a fixed amount of energy.
Examples: Latent Heat is usually a first-order phase change transition.
The first-order phase transition should have a change in volume and entropy.
For the first-order phase transition, the first-order derivative of Gibbs function change discontinuously.
As you know first-order phase transition occurs between the triple point and critical point.
Triple point:
In thermodynamics, the triple point is a point on a Pressure-temperature (P-T) diagram corresponding to temperature and pressure under which a substance can co-exist in equilibrium in all three phases of materials.
Phases of materials are Solid, liquid, gases states. The triple point is always unique.
