Suppose a small sample of pure X is held at 19. °C and 20.1 atm. What will be the state of the sample? solid Suppose the temperature is held constant at 19. °C but the pressure v (choose one) is decreased by 4.7 atm. What will happen to the sample? Nothing. It will melt. Suppose, on the other hand, the pressure is held constant at 20.1 atm It will freeze. but the temperature is decreased by 175. °C. What will happen to the sample? It will boil. It will condense. It will sublime. It will deposit. Explanation Check © 2022 McGraw Hill LLC. All Rights Reserved. Terms of Use pressure (atm)
