How does latent heat show up on phase diagram

WebWhen the water pressure increases at a given temperature to put the system into the liquid region of the water phase diagram, the water vapor is said to be supersaturated. This … Weblatent heat, or sometimes, a heat of transformation; we will say more about them later on. For now, note that when a pot of water boils, what happens is that the heat from the burner is absorbed by liquid water; as it absorbs the latent heat, the water is transformed into vapor (bubbles), which rise to the top and disperse. This process takes ...

WebIncreasing pressure p reduces the latent heat. How do I know? First, I happen to know the p-T (T is temperature) phase diagram of water (search this site or others to find it) , and at high p there’s a ’critical point’ at which the liquid-vapor change ceases to be a phase transition. So at high p the latent heat goes to zero.

WebThis is another great question. In 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.
