Question
**Using a Phase Diagram to Predict Phase at a Given Temperature**

**Study the following phase diagram of Substance X.**

The diagram presents a phase diagram with pressure (in atm) on the y-axis and temperature (in Kelvin) on the x-axis. The diagram is divided into three regions, labeled "solid," "liquid," and "gas," representing the respective phases of the substance:

- The "solid" region is at higher pressure and lower temperature.
- The "liquid" region is at moderate pressure and temperature.
- The "gas" region is at lower pressure and higher temperature.

There are curved lines marking the boundaries between these regions, indicating the conditions where phase transitions occur.

**Use this diagram to answer the following questions.**

1. **Suppose a small sample of pure X is held at 3°C and 9.6 atm. What will be the state of the sample?**
   - Options: [Choose one]

2. **Suppose the temperature is held constant at 3°C, but the pressure is decreased by 4.7 atm. What will happen to the sample?**
   - Options: [Choose one]

3. **Suppose, on the other hand, the pressure is held constant at 9.6 atm, but the temperature is decreased by 61°C. What will happen to the sample?**
   - Options: [Choose one: Nothing, It will melt, It will freeze, It will boil, It will condense, It will sublime, It will deposit]
