Study the following phase diagram of Substance X. pressure (atm) 32- 16- 0. solid liquid 200 gas 400 temperature (K) Use this diagram to answer the following questions. Suppose a small sample of pure X is held at -27. °C and 19.6 atm. What will be the state of the sample? Suppose the temperature is held constant at -27. °C but the pressure is decreased by 4.8 atm. What will happen to the sample? Suppose, on the other hand, the pressure is held constant at 19.6 atm but the temperature is decreased by 116. °C. What will happen to the sample? (choose one) ✓ (choose one) (choose one) (choose one) Nothing. It will melt. It will freeze. It will boil. It will condense. It will sublime. It will deposit.
