WebLet's see. 4 times 200 is 800, 800 times 100; yeah, that's about right. Now, we're dealing with 100 degree water vapor, and we have to turn that 100 degree water vapor to 110 degree vapor. So we use the specific heat of vapor. 1.89 joules per gram Kelvin. Multiplied by the amount of vapor we're dealing with, 200 grams. 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.

Webis called the latent heat; crossing the coexistence curve, the system releases (absorbs) a latent heatL. The entropy of the system changes abruptly: T 1 T L T Q ΔS = = δ The … WebThe initial conditions correspond to point A, which lies in the region of the phase diagram representing water vapor. Thus water at T = 400°C and P = 150 atm is a gas. B Cooling the … truths antonym

WebThe latent heat of sublimation is the amount of heat gained by a substance to convert its phase from solid to vapor or it is heat rejected by a substance while converting its phase from vapor to solid. Sublimation indicates the transition of the phase of the material from solid to vapor without entering into the liquid phase. WebSep 12, 2024 · Using the graph, if you know the pressure and temperature, you can determine the phase of water. The solid curves—boundaries between phases—indicate … WebThe methane phase diagram shows the phase behavior with changes in temperature and pressure. The curve between the critical point and the triple point shows the methane boiling point with changes in pressure. At the … philips hranice
