Study the following phase diagram of Substance X. 24 solid liquid gas 100 200 300 temperature (K) Use this diagram to answer the following questions. Suppose a small sample of pure X is held at -221. °C and 15.6 atm. (choose one) v What will the state of the sample? Suppose the temperature is held constant at -221. °C but the (choose one pressure is decreased by 7 atm. What will happen to the sample? (choose one) Nothing. It will melt. It will freeze. It will boil. It will condense. It will sublime. It will deposit. Suppose, on the other hand, the pressure is held constant at 15.6 atm but the temperature is increased by 160. °C. What will happen to the sample? pressure (atm)
