Question “Study the following phase diagram of Substance X. solid pressure (atm) liquid gas 100 200 temperature…”
Study the following phase diagram of Substance X. solid pressure (atm) liquid gas 100 200 temperature (K) Use this diagram to answer the following questions. Suppose a small sample of pure X is held at – 220 °C and 8.5 atm What will be the state of the sample? Ichoose one) choose one) Suppose the temperature is held constant at -220. °C but the pressure is decreased by 1.5 atm. What will happen to the sample? Suppose, on the other hand, the pressure is held constant at 8.5 atm but the temperature is increased by 128. “C. What will happen to the sample? choose one Nothing It w freeze boll it will conderile It will sublime it will deposit Explanation Check 2020 MG

Answer
Solution! – rn eiquid) solid ? gos, B 1.5 2e0degc T . Lao T = 220degc Point A = 8.5 atm. This indicates that the condition. Stade of the sample equid (6) T= 220degc, Pl=1.5ahu Point (6) indicates condition. so the eiquid forms gos stade (git will boil). I T = 220+128 348degC – 8.5 Atm
(117 dhnx is gos. H-region indicates rsp. so (b) To Conderse eine D must pross. IC) Point (c), moke righest top.
Conclusion
Above is the solution for “Study the following phase diagram of Substance X. solid pressure (atm) liquid gas 100 200 temperature…“. We hope that you find a good answer and gain the knowledge about this topic of engineering.
