Transcribed Image Text:Study the following phase diagram of Substance X. pressure (atm) 1.6- 0.8- solid 200 liquid temperature (K) 400 - gas Use this diagram to answer the following questions.
Suppose a small sample of pure X is held at 146. °C and 0.7 atm.
What will be the state of the sample?
Suppose the temperature is held constant at 146. °C but the pressure
is increased by 0.2 atm. What will happen to the sample?
Suppose, on the other hand, the pressure is held constant at 0.7 atm
but the temperature is decreased by 136. °C. What will happen to the
sample?
