This is because that specific... WebIn the video here, Sal uses a horizontal line through the phase diagram. 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

You can check here for more information: … 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. The "cooling rate" is the slope of the cooling curve at any ...

WebYes. The "Phase Shift" is: δ = 2πΔ/λ. with Δ = Optical Path Difference (OPD) = (n2 - n1) × t. where n2 is the refractive index of a sample medium (e.g. glass, air, etc.) and n1 is the refractive index of the surrounding medium (e.g. air) t is the thickness of the sample medium and λ is the wavelength of the light. Share. WebNov 27, 2024 · A phase change is when matter changes to from one state (solid, liquid, gas, plasma) to another. (see figure 1).
