What is the phase of a compound at 600 mmHg and 32oC if it melts at 35oC when pressure is 760 mmHg? Its triple point occurs at 200 mmHg and 36oC.

To determine the phase of a compound at a given temperature and pressure, you need to compare that temperature and pressure with the compound's phase diagram.

In this case, we know that the compound melts at 35°C when the pressure is 760 mmHg. We also know that its triple point occurs at 200 mmHg and 36°C.

Step 1: Analyze the given temperature and pressure:
- Temperature: 32°C
- Pressure: 600 mmHg

Step 2: Compare the given temperature and pressure with the compound's phase diagram:
- First, look at the given pressure (600 mmHg) and compare it to the triple point pressure (200 mmHg). Since the given pressure is higher than the triple point pressure, we can exclude the possibility of the compound being in the gas phase.
- Next, compare the given temperature (32°C) with the compound's melting point (35°C). Since the given temperature is lower than the melting point, we can conclude that the compound is not in the liquid phase.

Step 3: Determine the phase:
Since the compound is not in the gas or liquid phase, it must be in the solid phase.

Therefore, at 600 mmHg and 32°C, the compound is in the solid phase.
