Question
Study the following phase diagram of Substance X. Solid gas temperature (K) Use this diagram to answer the following questions. Suppose a small sample of pure X is held at 187. °C and l.2 atm What be the state of the sample solid liquid suppose the temperature is held constant at 187. OC but the pressure is increased by 0.9 atm what wil happen to the sample? Suppose, on the other hand, the pressure is held constant at 1.2 atm but the temperature is increased by 277. °C What will happen to the choose one sample suppose the temperature is held constant at 187. OC but the choose one) pressure is increased by 0.9 atm. What will happen to the sample Nothing It will melt. Suppose, on the other hand, the pressure is held constant at 1.2 atm It will freeze. but the temperature is increased by 277. CC what will happen to the It will boil. sample? It will condense It wi sublime. It will deposition. Suppose, on the other hand, the pressure is held constant at 1.2 atm l 277. °C. What will happen to the v choose one) but the temperature is increased by sample? melt. It will freeze It will boil. It will condense. It will sublime. deposition.Explanation / Answer
1. At -187 oC (86 K) and 1.2 atm- sample will be in solid state
2.At -187 oC (86 K) and 1.2+0.9=2.1 atm- sample will still be in solid state
3. At -187+277= 90 oC (363 K) and 1.2 atm, sample will be in liquid state
4. At -187 oC (86 K) and 1.2+0.9=2.1 atm- nothing will happen to the sample
5.At -187+277= 90 oC (363 K) and 1.2 atm, sample will melt. It goes from solid at -187 oC to liquid if you increase the tempearture by 277 oC
