Identify the stable phase at the given temperature and pressure.Temperature:  42 KPressure:  152 atm

To identify the stable phase of a substance at a given temperature and pressure, we typically refer to a phase diagram, which is a graphical representation of the physical states of a substance under different temperatures and pressures.

However, without knowing the specific substance in question, it's impossible to provide an accurate answer. Different substances have different phase diagrams and therefore, behave differently under various conditions of temperature and pressure.

For example, if we were talking about water, at 42 K (which is far below the freezing point of water at 1 atm pressure), water would be in the solid phase (ice). But the pressure is also extremely high (152 atm), which could potentially alter the phase depending on the specific phase diagram of the substance.

So, to provide an accurate answer, we would need to know the specific substance in question.
