WebPhase change occurs due to... the particles colliding ad the faster moving particles slow down and the slower moving particles speed up (same with momentum). Temperature of warmer substance... drops as its kinetic energy is lost. Temperature of the cooler substance... increases as energy is gained. Thermal Equilibrium WebNov 5, 2024 · When the path crosses a boundary line, a phase change occurs. Names for Phase Changes Each boundary crossing has its own name depending on the direction the boundary is crossed. When moving from the solid phase to the liquid phase across the solid/liquid boundary, the material is melting.

WebWhen the phase change occurs, there is a "thermal arrest"; that is, the temperature stays constant. This is because the matter has more internal energy as a liquid or gas than in the state that it is cooling to. The amount of energy required for a phase change is known as latent heat.

But, it doesn't have to be horizontal. Imagine a vertical line through this diagram-- for water, choose 100 degrees C. As long as you are at 100 C, you can change the phase by changing the pressure on the system. This kind of process is called "adiabatic". 2 comments smart gun product liability
